Philips screws are awful. They strip if you look at them wrong. Flatheads should only be used on thumbscrews just in case you need a little extra torque from a screwdriver.
Torx and Hex are excellent.
I work on electronics and woodworking and Phillips are the utter worst of both of them. The thread lock in computers makes them easy to strip when unscrewing. The resistance of driving them into wood makes them guaranteed to strip when screwing. Fuck them.
The big issue I see with people driving Phillips screws is that they don't use a large enough driver size. Computer screws for example are Phillips #2 and I've never had an issue with them stripping.
Maybe I'm just being lucky but I've never experienced screws stripping anymore since I've started getting better tools for myself.
And in woodworking it can also help to pre-drill a hole using your smallest drill, before screwing a screw in. This also prevents the wood from cracking. I've also seen wood screws that have some lubrication pre-applied.
Could be that it's not a Philips but a JIS. I didn't even know that JIS existed until a couple years ago. The shape is close enough to Philips to mostly work but make it super easy to strip.
Torx gang unite.
We had our 20 y/o deck repaired and stained last year. I was chatting with the overseer about what he was going to do and the topic of screws came up; he said he was going to use Torx, and only ever used Torx anymore - I just about cheered.
I'd been losing hope in humanity lately, but little signs of sanity like this, professionals finally getting rid of the hell-bits that are Phillips heads, lifts my heart and gives me hope.
These days, all but the cheapest outdoor-grade screws in the US are torx, generally with a bit thrown into the box that, while cheap, should work fine for a few boxes' worth.
I work at a big box hardware store, and I can confirm that almost all deck and structural screws are moving to torx. (much to the older generations dismay)
I've heard that was more of a European thing, but the only two serious contenders are Pozidriv vs Torx for screws (and hex vs Allen for bolts).
I just checked my local hardware store's website, and out of the 176 kinds of 4/4.5mm screw boxes in their inventory, 74 are Torx, 55 are Pozidriv, and 38 are Phillips (ew).
Either Torx or Pozidriv is fine when used properly, however most DIYers don't understand the difference between PZ and PH and end up stripping their heads. Also it's much harder to use the wrong-sized bit with Torx than PZ.
So yeah, Torx wins in just about every category and other heads only get manufactured to appease old people and penny-pinchers.
I'm not sure I've ever seen a philips or slotted deck screw. I have and have purchased many boxes of these things and they've always been nearly 100% Robertson. Is this a US thing?
The image feels like it should be posted in c/unpopularopinions
Flatheads should only be used on thumbscrews just in case you need a little extra torque from a screwdriver.
The only other legitimate use I've seen for flatheads is on wooden boats, where you'll be gooping the head up with tar for waterproofing. Since you'll eventually have to scrape it back off again to get to the fastener, you want a simple geometry that's easy to clean.
Square (Robertson) drives are actually great too. Better than Hex/Allen, but Torx is the most reliable, and the most German. Phillips can take a long walk off a short pier.
I do wish Robertson heads were more common. They're almost as tough as torx, but tapered to stick on the tip of the tool, which is so convenient.
The ones with bumps in the middle can go fuck themselves
Square is nice too but square/Phillips is a good damn lie. Because the Philips side of it doesn't work well enough so it is still just a square but with extra slots
I feel like spanner would be the best for not having shit getting stripped. But that's just looking at this diagram; never seen them IRL.
They're mostly just used for tamper-proof screws for things like bathroom stalls so people can't take them apart as a "prank" or whatever. The screw driver bits tend to break easily, which is usually worse than the screw stripping.
Hexagons are the bestagons
Fuck this. Torx, Hex, square drive are all positive engagement. Phillips is literally designed to cam out. Slotted is just the first head type to have existed because of how easy it is to make, but is far inferior to every other type.
A good square bit for my impact is a lifesaver as an electrician. Pretty much every conduit fitting set screw can take flat, Philips, or square. When you're reaching out one-handed from the top of a ladder, you really don't want to cam out all the time.
Flat head screws are necessary when at a very small scale like in watchmaking.
Really not a fan of Hex (it just cams out way too easily) but Torx is like screwdriver orgasm. Philips just feels like intentionally bad design
Philips just feels like intentionally bad design
Philips are designed the way they are so that they "cam out". Meaning if too much force is applied to the screw, the driver will intentionally pop out to avoid damaging the tool or the fastener. Its a feature, not a flaw. A Robertson (square), torx, or hex will let you apply enough force until the screw or the driver fail catastrophically.
If you've tried to do any large amount of work with slotted, you'll know that it belongs in Mental Disorders. I'll take Six-Lobe/Torx over phillips or slotted any day of the week.
Yea but fuck the security torx screws. Also hot take, but underrated screw goes to tri-wing/Y. They'd be great screws if they weren't security screws as well.
Also hot take, but underrated screw goes to tri-wing
Is that a hot take? Everyone I've ever mentioned them to who knows what they are immediately starts shit talking both them and Nintendo for making us buy a screwdriver for one set of devices in our lives
You can just get a pack of security bits from HF or online.
Wow, person making this chart actually has no clue. First two are absolute worst nightmare. Torx, Pozidrive, JIS, Alan all great with minimum damage.
It's the "grandpa has been using slotted all his life so it can't be bad" reasoning. I can't think of a single use case I'd want slotted or even philips, if I've got a choice. Torx or bust!
If you're having trouble with Torx, buy better screws and bits. There are so many terrible screws around. The difference between a deep well fitting head and the cheap trash is massive.
Yea, I had quite the wtf moment one time when I stripped a Torx screw.
If you're having trouble with Torx, buy better screws and bits.
Last year I needed to do some hardwood construction outdoors. On the advise of a carpenter I ordered some high quality stainless steel Torx screws online. They don’t sell these in the consumer-oriented DIY store. They were awesome, much harder than the cheap screws, that would easily bend when driven into hardwood, much sharper as well and if you buy a box of 100 or more it comes with a bit which fits perfectly. So much easier to use than the overpriced crap from the DIY store.
Most of us are dealing with screws that someone else installed, though. Can't really control the fact that the manufacturer decided to save .5 cents per units by using cheapass screws that strip if you look at them.
slotted screws are all fun and games, but if they're ruined...you will never get them out. I coursed these screws. Eventually they got the dremel treatement.
Can't say I've ever had fun with slotted screw.
Yes!
You can tell a shitpost is a shitpost when it is entirely wrong
Slotted is absolute shit. Philips is acceptable if you must live in the 1900s.
Torx all the way. Every other type should be illegal and punishable by death of perpetrator's extended family.
Robertson, or square is the best. Screw will literally stay in the screw without dropping.
Pozidrive and torx ftw. The rest can bugger off tbh.
Also, temper proof torx makes me lol. Brb, grabbing pliers to break of the temper proof bit haha
This is the way
the only slightly justifiable use of slotted is something like the face plate on a light switch or power outlet, where it doesn't have to be particularly tight and it's nice you can remove it in a pinch with a fingernail or dime.
.. but really if someone came and replaced all of mine with torx I can't say id complain, so its not like they're good in that use case.. just less awful
I'm sorry, calling Robertson "square" is insulting to a superior screw design and fuck you for even pretending it isn't.
6 "lobe" is torx too. Nobody calls Allen bolts hexagon either.
I don't think I've ever heard that fastener called an Allen bolt, just the tool (Allen key). I've generally heard them called hex sockets heads. Maybe it's a regional thing?
Just rude, really.
Nobody calls Allen bolts hexagon either.
That's not true when working internationally, since it can have different names in different nations. In Italy is Brugola, in Germany Inbus and in other places it has other names. Everyone understands what a hex key is though
Agreed, but I often hear Allen keys referred to as hex keys. I don't think I've ever seen anyone confused by that though.
It’s a crime against safe screwing to dis Robertson like that.
Everyone who does not want torx and nothing but torx has never screwed torx screws.
Honestly, I dont understand why everything isnt square drive.
its simple, and its a pretty strong design that resists camming out and rounding off.
Some claim to have stripped Robertson screws but to be fair, the metal used and amount of torque the peson applies is the biggest reason for problems.
Phillips heads were supposed to solve the over torquing problem, but everyone didn't listen to standard specifications and didn't bother using them as they were meant to be made and used. The Philips head was supposed to slip once the correct torque was applied. Unfortunately, this positive benefit became a negative. With poor metals and a mismatched driver bit to screw head along with not using the screw head that was meant for the specified torque demands, the Phillips screw became known for stripping.
Trying to implement non overtorquing feature to the square bit and you will find how similar it will look to the Phillips head.
Right now, Torx is the best at not stripping, but good luck if the screw is overtorqued. Eventually, the cheap metal gives out with the screw head, or bit, snapping off.
Fuck large format torx that are exposed to the element. I just weld a nut on them now and pound them out with an impact because you'll break 2 torx bits for every one bolt you'd get out.
Torx are cancer.
There is one screw on this chart that I have a mortal hatred for. Just one. That being the fat Phillips (called "Phillips/square" on this chart meme thing).
I have no idea why, but some companies can't resist the sadistic urge to put tiny versions of these fuckers on equipment that should just use a torque or Phillips screw head. But no, they want you to truly suffer. Because they don't stop there: they make the fragile little fuckers out of NICKEL. Which means they are extra malleable and prone to strip if you so much as look at them the wrong way. So imagine you need to replace a hard drive on a RAID-type storage pool that's already down two spares and you can't fucking get the drive out of it's sled because the vendor not only hired a bodybuilder to tighten the screws, but simultaneously chose the worst possible metal just for giggles and chose the screw head that they no body will have the proper bit for and will inevitably use a normal phillips on until it strips.
I now have a ritual procedure of putting every drive that gets replaced in the coldest cold aisle in the datacenter for at least 5 minutes just to make these fucking screws less likely to ruin my day.
Fuck whoever invented the fat phillips, even the lowest ring of hell is too good for them.
But no, they want you to truly suffer.
It's called Planned Obsolescence, sweatie. Now go out and buy a new device.
Buddy. I'm not talking about consumer equipment. I'm talking about enterprise equipment that costs more than your car. Step off.
And yes, I know planned obsolescence is a thing in enterprise. But that doesn't mean your enterprise customer won't make purchasing decisions based on the quality of such small components. We refuse to order from HPE, to give you an idea of how we take this sort of thing. We know what we're buying and how to use it and if we can't properly maintain it because the vendor is an asshat, we'll find a new vendor because fuck you we can't afford to put up with your shenanigans.
Ya. Just those guys, and anybody who eats turtles. Keep the psychos out of the nice parts of hell.
Every awkward fascist, sexist turtle will be gathered into an imaginary pot and cooked alive for all to see. The aroma and broth will be delectable.
If you have no idea what any of this means and no idea why I don this weird username, then I kindly implore you stay out of it for sake of your own sanity. Otherwise, lmk and I'll begrudgingly curse you with knowledge of the tale of a particularly disgraceful misanthrope and an even worse excuse for a human being.
A lot of those wacky screws exist solely to keep people from randomly messing with them. You have to really go out of your way the get the right tool for the job, and that's if there even is one.
Like the one-way screws holding together bathroom stalls.
Those screws can fuck right off. Almost every bathroom stall installed today uses a security torx tip.
Edit: Forgot to clarify, the one way slotted screws can fuck right off.
Yup, I've noticed that spanner screws (the two dots) are usually found on elevator control panels. There is no reason that somebody should be able to open those up with a Swiss army knife.
It's funny because I've opened those screws on something else using a bit of effort and the scissors on my swiss army knife.
I'm American and even i can agree Robertson are the goat.
Phillips and flat suck. Not enough surface area on Phillips, resulting in stripped screws. And getting centered on flat sucks.
Robertson drive, just pop your driver in and it's self centering, lots of surface contact to drive, and lots of meat on the head to prevent stripping. Anything more than 4 edges is unnecessary.
You are now an honary Canadian.
Where my hex fans at?
Torx crew represent!
Fuck yea
Square Drive Gang would like to battle!
Fuck yea.
❤
Let me introduce a fresh hell: we call them Apex screws.
No take it back
German engineering?
Wonder what gave away...
Torx is the only screw I buy when I buy screws. All the phillipses and other shit screws I have were included with some other shit I bought.
Why is that? Do they last longer than Phillips?
They can take more torque, don't cam out when screwing and most importantly can't be damaged easily by constantly using the screw, unlike Philips which fucks off after second attempt.
I've never seen Torx screws on any shelf in France. Perhaps I'm not looking in the right place, but everything is fucking Philips. Everything
Slot screws are the worst of them all...
I hate slot screws because they are easy to slip out of, and the place that I find them the most is always outlet covers. Like... What the fuck? Why are you gonna put the most easy to slip out of screw next to the most dangerous to slip into hole?!
No thanks. I will stick to my torx and hex, and they better be in metric.
Penta-lobes for some of the small electronics are funny I guess, but they don't bother me as long as I have a bit for it. Main thing is to understand why some of these different shapes exist.
Torx doesn't come in standard/metric. It uses an arbitrary system. What's so "25" about a T25?
Ah yes, the head size follows their iso standard for it. The threads, however, can be metric or SAE. You can put a different screw/bolt with whatever head in the same hole, but the threads/diameter can be metric or SAE/imperial.
Flatheads are good for a few specific applications that require the head to have flat contact with the surface but not be tall enough to be something else like a hex or torx, but needing a lot of torque. They suck for everything else.
Specific applications like... prying, poking, scraping, and chiseling.
Also handy on horrible cheap raised hex bolts when they get stripped. Dremel a slot and you're done.
There are low profile hex heads that exist for that same purpose though. Pretty much no need nowadays for slotted heads, except at very small scale.
You obviously haven't ever worked in construction.
T-20 T-25 T-30
Square heads (Robinson) are used by millwork guys (cabinets)
Hex head are also used a lot
Edit: Also the fucking electrical screws that home depot only sells ONE FUCKING SCREW DRIVER FOR and its in a 3 pack of Milwaukee electricians insulated screwdrivers, it's ECX 1 and 2
Robinson are great
where are they called slotted, I have only ever heard them called flat.
That's another american/british English thing
I actually really like Philips with slot because it's just a Philips with a slot for when the Philips gets stripped so the two on the bottom right corner are the best in my opinion because if one ether the flat head or the Philips gets stripped you can just grab a ratchet or spanner
Which is nice because the Philips always gets stripped.
"when the Phillips gets stripped"
Boys I think this indicates a problem
If you have a quality bit and quality fastener it's quite difficult to cam out a Phillips. The issue is that finding quality bits and fasteners can be difficult and expensive so most people have experience with the homeowner grade which cams out easily without a huge amount of pressure.
Why not just use a ratchet or spanner then...?
Because sometimes that might be stripped so you have to use ether the flat head or Philips
Whoever drew this deserves eternal damnation!
Phillips are for boring fuckin normies who can't chooch
Speaking of chooch, anyone know what's up with AvE?
Aside from going out of his mind during covid?
Not unlike WranglerStar.
Still a nutter, as far as I know.
Had to unsub and strike him from my feed when he started cheering for the "freedom convoy" donkeys a while back. Revealed himself to be a hopelessly stupid and ignorant bumblefuck in my book. Fuck him.
You'll call a Phillips a Phillips but not a Robertson a Robertson or an Allen an Allen, smh
My boy, you do NOT do Robinson dirty like that.
Square wishing he was as famous as Phillips, sad.
"Robinson"!?!
I'm sorry but you're going to have to hand in your passport.
Oh no! I am forever shamed 😭
Fuuuuckin hell, I haven't seen a slotted screw since the 1980s. Philips screws are exclusively for electrical.
Is this yet another way the US has dropped 30 years behind modern countries?
They make bad screw heads but the drivers themselves are useful for so many random odd-jobs that you can basically be guaranteed to find a flathead that'll fit your screw within a few seconds of searching near basically any tools
Because of that many cheaper companies use flats for their screws, though I almost never see it in anything bigger than the little ass plugs we use in doorknobs and electrical socket covers. Once you go bigger than those it's usually a Phillips/flat combo, or torx if you're spending some extra cash
Oh god yeah I still use flat screwdrivers on a daily basis, basically as levers
"Little ass plugs" are called "grub screws" btw 😂
In 30 years you'll catch up and they'll all be 2.5mm Allen screws. I do remember them being slotted, it was a massive pain to find a screwdriver that fitted!
Yeah hex or torx it is. Everything else can burn in hell
I submit that every screw in the world should be the six lobe slotted. For the stuff that’s not tamper-resistant, anyway.
You have the six lobe for actually building things, because fuck Phillips head screws, and the slot for convenience where you could use anything from a coin to a knife.
Here in the US, certain brands of deck screws for outdoor use are six lobe and they come with the driver bit in the box because everybody has the damn Phillips and flat head screwdrivers! But to be fair, if you have a bunch of tools you probably also have a set of torx drivers.
Torx master race has entered the chat.
Literally the only people who I hear say negative things about Torx / star bits are people who don't own a good Torx driver set. They don't strip easily (using the correct size) and they don't slip.
my dislike of them is soly because the multi tools I carry do not usualy have bits for them.
if you need to unscrew a torx screw and you don't have any torx bits, you can try using a flathead. it won't work and you'll probably get hurt doing it, but you can try it.
Sometimes an allen wrench can be found which will fit. Still a shitty option, but better than flathead usually.
Thanks, I think I'll try this next time.
I'm a slotted screw HATER
Everything electrical uses them and it's a nightmare keeping the screwdriver aligned properly to try and take them out at a good speed
My favorite would be square drive but they always seem to make those out of recycled ham sandwiches or something
Come to Canada, most of our existing stuff is robertson, and only the really cheap new stuff isn't.
All IKEA furniture uses Pozidriv (no “e”, it’s a trademark). Not going to say if that’s good or bad, but operating a Pozidriv with a Phillips is always going to be terrible.
Pozidriv is basically Philips++.
What the actual fuck is a 'S type' screw? What purpose does that have that another normal screw type cannot provide? What madness is this?!
Easy to screw closed but not open. Gotta think about it in 3 dimensions. They are used in US bathroom stalls.
To elaborate: it's in 3d, the s curve is a ramp. The regular screwdriver slots in when turned clockwise, but has no purchase the other way round. It slips out because the ramp lifts the screwdriver out of the screw.
You can screw but can't unscrew because it lifts the driver.
Op has never done any serious screw work it seems
I'm seeing a lot of people here claiming that the Philips head was originally designed to cam out/strip to prevent a transfer of force sufficient to twist the head off. While I agree this does sound logically plausible, I could find no reference to such features in the original patent: https://patentimages.storage.googleapis.com/0f/28/e3/3e3075abbb9779/US2046837.pdf 🤷♂️
Yup. "Cam action" is only mentioned in the context of the wedge shaped driver/bit squishing out any crud that had lodged itself in the screw. The entire idea was self-centering and better engagement between the driver and screw due to the wedging. The fact that it failed more gracefully is a side benefit at most, and more likely just sales fluff to compete against Robertson.
To be fair, I have snapped a few Robertson in my day, certainly higher by percent than the number of Phillips I've used, but that's more than balanced out by the huge number of crappy Phillips heads that have been almost as totally ruined by camming out under fairly normal use with a properly fitted driver.
No mention of JIS which is yet another "fuck Phillips" argument
I got a dinky electronics repair kit that included a wide range of those bits and god DAMN. It feels like they outperform phillips heads on phillips fasteners.
Does that mean that I'm using a Phillips driver on things that are actually JIS? A lot of electronics are Japanese.
Probably. I find a JIS driver is, for the most part, slightly better for a lot of what I do.
The main thing I've found is you dont want too much of a point on the bit end. Too pointy and the driver will just wobble on the point and strip everything out.
JIS is more common on Japanese machines, ie Japanese cars and motorcycles. When I was a bike mechanic you used JIS for Shimano derailleur adjustment screws. Even tho a Phillips "fit" it would destroy the screw.
I actually can't tell them apart from sight truth be told, but I'm also not wrenching anymore (not to mention the cycling industry largely moved on to hex and torx)
Factually incorrect.
Torx and Square/Robertson are superior, Hex/Allen and Phillips are allowed a seat on this council but not granted the rank of master, Posidriv is theoretically Phillips++ but only to the six people in the world that know what it is and own a Posidriv screwdriver, to everyone else it's that goddamn Phillips that keeps camming out. JIS is parallel universe Phillips, it's exactly as reasonably okay as Phillips is for identical reasons, the biggest problem is that they exist alongside and closely resemble Phillips screws. Everything else except slotted is a mental disorder, and slotted was dropped on its head as a child.
Posidrive is very common in the UK. Especially in trades. They are so common screwdriver sets will include posi and slotted with no Philips. Philips is still common in electronics.
Posidrive is much better than Phillips, but just as easy to quickly screw lots of things. Torx and hex take longer to align and have many more sized drive ends. Posidrive has three sizes and 90% of them are number 2. But if you need more torque then they are no good. But at that point you need to switch to a different tool like an impact or wrench.
A washing machine I recently had to repair had three different sizes of torx and it isn't obvious which one till you test fit. Posidrive is easy to identify the size by eye and many different screw diameters share the same posi head. Coupled with self alignment they are just more convenient. I have Robertson bits from multipacks but never needed them.
Personally I wish we could eliminate flathead screw.
I seem to do that every time I try to use one.
I think it has its place in things that need to be fixed in the field where you may not have access to a screwdriver. Other than that they kinda suck
There's a distinct lack of love for pozidrive here. It's like Phillips but without being shit.
I worked for an engineering company that used them almost exclusively and now I won't shut the fuck up about pozidriv l. everyone thinks I'm insane
I agree. The vast majority of people don't know the difference, and have never used a pozidriv driver with a pozidriv screw. It is a vast improvement imo.
Don't think I've ever seen one before.
Might be regional? It's the go-to in the UK for a lot of screws.
We're screwed
The worst one I ever came across was five lobe tamperproof on a Seagate external hdd. Couldn't find any bits for it that didn't have to be imported. Ended with a rather destructive disassembly
Pentalobe screws are used by Apple, was surprised not to see them listed. They also use a strange tri on some old batteries.
Best is to mold one directly from the screwhead using molten iron issued from your local weaponsmith.
Phillips and pozi are actually designed to cam out (look it up on wikipedia). Started using torx a few years ago and I will never go back to pz again, even if it's on the clock and someone else is paying for materials.
Flat head still has it's place IMO, for example on machinery that gets used out in the field where you might need to improvise a driver out of a knife or coin or something.
Ph and pz are the work of the devil though.
This man clearly works in the field. Torx is the head to rule them all, except below T15 then it's a pain, and you break more bits than you put in screws.
True. Best to save T15 and below for cleaning the flesh out from under your fingernails after you've finished removing all the pz screws the last guy put in.
Torx and PZ ftw.
Also, I'd like to apologise to the future owner of my house for making several constructions using both in no particular order.
Holy hell the entirety of Lemmy just exposed themselves as retarded jobless people.
Six lobe, or torx, is fucking awesome when screwing in serious screws. It's the reason why it replaced all philips and most hex heads.
Slotted screws are the fucking worst. You guys have never worked a blue collar job in your lives 🤣😂😭
My first thought was, "this post brought to you by not mechanics." Otherwise they'd recognize the superiority of hex and torx over Philips and especially flat. But then I realized this is, in fact, a very shit post.
They y-type screw is obnoxious.
I've only encountered those on Nintendo products, they are the worst.
I came here to show love for Robertson, but it looks like I didn't need to. You guys are the best. 😁
Ahh, Lemmy shit post, makes sense now
They 100% got me until I saw your post, I was just about ready to start proselytizing for our lord and saivor the Torx bit.
Clutch screw aka the green lantern corp screw
I will also allow hex. Anything else can get fucked
Hex stripped even when using the correct size likely due to a seized part.
Yeah, I've had hex strip before as well. It's always been on the smaller sizes for me though at least. Like sub M3 or 1/8" ish. And of course, cheap hex keys are just asking for it at those sizes. On the other hand, I've definitely never had a torx head strip out on me.
Robertson is fine, much much better than Philips, and cheaper to manufacture than torx.or hex.
Cue all the Canadians pretending anyone gives a shit about their goofy chamfered square deck screws.
I don't know what you're talking about. They're naturally superior.
Apparently I don't know shit about handywork since everyone here is swooning about Torx and I don't even have an idea what they are
The best goddamn type of screw you will ever screw. No slipping, no stripping - you torque, it goes in.
Probably the best shitpost I've seen in a while.
