Screw drive arguments are my absolute favorite, thank you OP for posting such divisive content!
RIP
Same - this will easily be my favorite post of the day, and it’s still early.
Star bit.
That isn’t a thing ~~~~
That’s what I’ve always called them
I’m just keeping with the adversity of the discussion, so your opinion is inferior to my superior choice of drive and terminology
Are you at well I totally prefer x screwdrivers over negative screwdrivers
Calling it a square not a Robinson makes me doubt everything else on this including the ones I know are right.
Same with 6 lobe instead of torx
Or 6 lobe tamper: security torx. Or hexagon: Allan key. Seriously.
Are you certain about that spelling? Interesting if so
Sometimes we use “hex key” for Allen wrench
Torx is a trademarked name, 6 lobe is generic Torx.
Like how everybody calls a tissue a Kleenex.
Or a personal watercraft a Jet Ski
It’s like the old joke tagline that Dyson had at one point.
“Dyson, the last name in Hoovers”.
Weird, I’ve only ever heard torx and square.
in america everything must be named after a company
also isn’t it Robertson?
A square screw is a Robinson, fyi.
“No! The RED-handled Robbie screwdriver! And hold the light steady” is like half my experiences with my dad. :-D Such a red-foreman.
Robertson
There’s some anti-Canadian bias in this chart for sure.
Don’t call Philips after the inventor but Robertson after the shape.
It’s less bias and more poor advertising awareness in the US and the rest of the world. Still, it does not diminish the simple effectiveness of the design.

Also the 6 lobe or whatever it’s called in the diagram is usually called a torx.
Robinson ftw though.
Edit: Robertson, not Robinson…damn autocorrect.
Robertson
Hahaha. Thanks, I didn’t even notice. Damn autocorrect.
“Square”? “SQUARE”??!! Excuse me, we fought a patent war over Robertson drive, and WE FUCKING WON.
Came here to say this
Square exists. Robertson isn’t depicted. Probably because only Canadians and some really odd USA deckbuilders use it.
And “hexagon” is allan key.
Tag yourself I’m cheese square
If you’re talking about the piefed tags, we need an auto tagger of some sort. I do not use tags for anything outside of AI fine tuning and training. I do not know the scope of use, and creating a bunch of single occurrence tags is beyond useless like what archive dot org has devolved into. We must have a system like gelbooru/danbooru for tags selection and moderation if that is to be sustainable or useful over time… or I simply do not understand the use scope.
Its a meme
Wait, cheese? I’ll take twenty
The first two are screw heads. The rest are mental illnesses.
Phillips slot is very hand tbf, you have a phillips screwdriver? Good you will have good grip, you don’t have one? Good you will still be able to unscrew that
I’ll give you that but all the others are in my opinion completely unnecessary and just cause issues. To me anything other than a Philips head is completely unnecessary and deliberately over complicated.
No way. Torx over Phillips all day
No because no one has a screwdriver that can fit it, they have to go out and explicitly buy one just so they can undo a screw.
Unless something really super duper seriously needs to stay tightened a Phillips is the way to go. I don’t want to have to start a project only to have to go out and buy something that I’ll only ever use once because it’s some weird exotic screw head. Phillips is what data centres use to secure computers to server racks so it’s obviously pretty good.
That just means it works OK for cheap flimsy sheet metal. But the philips head was originally designed to be a torque limiting fastener for assembly line use. It’s supposed to cam out when the worker’s simple air tool had the screw tightened down.
If it works, it works. But I wouldn’t want to be driving Phillips head screws into wood when I’m building something.
Carpenters these days almost exclusively use torx, drywall still uses Philips I guess. Also I only ever use a hand screwdriver with bolts unless something has gone very wrong. If we’re screwing I’ve got to use an impact driver, and finding a torx bit is super easy for those. They usually come in the box of screws.
I like the sentiment that there should be one awesome screw head used everywhere, even if it wouldn’t ever 100% happen.
But phillips head is garbage. I agree with the other reply: torx all day long. Honestly, many of the others are good designs that could likewise handle a lot of torque with less tendency to cam out. But torx has kind of already become that standard, at least around me in the US.
And, in my experience, it’s proven itself in the field. My non-tech hobbies have involved a lot of outdoor construction this year. I used an impact driver to bury big 6" screws all the way into pressure treated lumber about 1,000 times, and then about a thousand other smaller 2.5" - 3.5" outdoor screws. All of them were torx.
And subjectively, the bit engages like a cylindrical gear but without any sharp corners. It seems like it should be easier to clean a screw dropped in the mud. I’ve had to do that more than once, but I didn’t do a comparison, lol.

Likewise!
I get a better grip with slot than Phillips, which is good if I’m using an electric screwdriver and want to cam out at a certain torque
Slotted screws should have gone away after the 1800s. God, I hate them so much.
I’m looking for a Six-Lobe Tamper Cheese screw.
Sub to your mcMaster
They missed one
This guide is trash, they don’t even know the proper names.
I’d like to go on record as saying six-lobe tamper can die in a fire.
Use a hammer and punch to break off the pin.
Wonder what the usecase for “H-type” would be
Anti-tamper.
I’ve seen them used to screw together toilet stalls in public bathrooms. Stops bored crackheads disassembling them.
For vocalists, if the only tool they have is a tuning fork.
Anti tamper and devices not intended to be opened. Ive seen them on european power bricks and blocks
usecase
use-case, right?
trolling someone
A mildly tamper proof fastener.
I hate phillips head screws with every fiber of my being. All they are good at is becoming stripped.
Pozidrive for the win.
I prefer torx (six lobe in this picture)
I do too, but i was referring to a philips alternative.
You would be correct. Except philip head screws were never really meant to be removed. They were originally designed to be a simple torque limiting fastener for use on an assembly line to speed up the work. I think the screw type was developed for Ford Motor’s use on assembly lines in the 1920s. The installation tool is meant to cam out of the slots when the screw hits the proper limit. So one and done. The issue is today designers are often too stupid/lazy to not distinguish between assemblies that need to be taken apart to repair and those that won’t be.
And THEN the Japanese walk into this mess by introducing their JIS spec cross-head screws and special drivers. It’s very close to the original philips in looks, but it’s not. It’s designed to not cam out as easily as a philips head screw and be reusable. And It requires a special set of JIS screwdrivers to install or remove. They are commonly found on Japanese motorcycles. Though they have spread and can be found in the weirdest places these days.
So if you have a “philips head” screw you just can’t remove, it just might be JIS. So buy a set of JIS drivers, and look very closely, and “try before you pry” to be sure you are getting the correct fit between the driver and the screw head.
Just wait until you have to remove some old slotted screws! Phillips are great compared to them. My house was build in 1925, I think slotted was the only option back in those days…
Found this on Wikipedia “The credited inventor of the Phillips screw was John P. Thompson who, in 1932, patented (#1,908,080) a recessed cruciform screw and in 1933, a screwdriver for it.”
You would think the screw and screwdriver would come hand in hand the same year. But I guess even he struggled with how to not strip them.
They are better than slotted. The driver always slips and you always stab yourself in the arm, they are impossible to work with. Why were they even invented, what purpose do they solve, it is literally the worst possible way to design a screw.
The problem you have with slotted screw heads is twofold.
-
You buy the cheapest and crappiest set of straight bladed drivers the dollar store sells. Manufactured by some poor Pakistani dude squatting in the dirt and wearing his safety squints and safety sandals as he bashes each one out with a hammer and scrap steel anvil.
-
You have no idea that those drivers are actually meant to be fitted to the slotted screw you are working with. Not that it matters, you won’t take the time and effort to do so anyway.
A good set of straight blade screw drivers cost real money. They a forged and then the tips are hollow ground to get purchase in the slot to prevent cam out. Check the cost of a set of gunsmithing screwdrivers. And no one that actually has a set or two of those is afraid to modify the tips to correctly make the screwdriver, (or as the British so elegantly put it-- turnscrews back in the day), fit the slot.
While we have far better designs these days, they are complicated to make and require special tooling to manufacture. And a big advantage to the slotted screw is if you strip out one of those much fancier types, you can often just take a small flat file and pretty quickly cut a slot to try again. (looking at you Philips head).
-
Flatheads are typically used in situations where you want to discourage using a driver because it may over torque the screw and cause damage such as in an outlet cover.
Slotted is still useful today, but as a bolt instead of a screw. They are fantastic for applications where you can’t assume someone has a screwdriver.
They work OK as machine screws these days. But I still far prefer socket hexhead screws.
O the other hand, I have dabbled in the gunsmithing repair of old antique firearms. I have a taste for fine old British SxS shotguns. And they often needed repairs to put them back in service. They use nothing but slotted screws to this day.
And honestly, there is something in my toolmaker’s brain that feels so good when I gaze upon a fine old shotgun and see every screw slot is timed to be in perfect alignment and every screw meticulously hand fitted to make it so. The extra time and effort to do that speaks to the care and craftsmanship of the 'smith that built that gun. It’s a level of craftsmanship we no longer see in the day to day world anymore.
I should specify that they work better when all you have is a knife, coin, or cartridge. to unscrew things. My avalanche beacon has a slotted screw for the battery for example, but guns are another one.
Your beacon maybe has a coin slot that’s a more universal type for real emergency things like your beacon or a small child’s battery operated toy.
I’m confused, are you saying avalanche beacons are children’s toys or emergency things? Childrens toys in my experience use Philips head screws.
They are the easiest to machine, so they were invented first. Being first and being cheap leads to abundance. Ubiquity means every toolbox needs a flathead screwdriver, and most of those also prove useful as prybars.
My father in law converted a #4 slot into a chisel using his grinder.
Anything in the bottom two rows (other than hex) and you are welcome to curse the ancestry of the person who decided to use that type of fastener.
