Nice drawing, but how exactly is this a guide?
I would actually love to see explanation of what is best use case for the screws (the first two rows)
Try designing stuff to share with people in CAD. You’ll quickly learn to collect such references.
You only need Torx screws (six-lobe) The only reason to have a bit set with the rest of the heads is so that you can remove an old fastener and replace it with torx.
Wonder what the usecase for “H-type” would be
usecase
use-case, right?
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.
As written by others: Anti-tamper and proof of tamper. Not only can you make it harder to open the case, but you can also intentionally use bits for manufacturing that are non-standard(e.g. leave a little bit of the inner or outer part out) and when you get a device back that has a fully used screw you can tell the customer to fuck right off with their claim.
Especially for medical devices that is sometimes done - and tbf,understandable as there are devices that really really shouldn’t be opened by anyone who is not manufacturer associated.
A square screw is a Robinson, fyi.
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.
“No! The RED-handled Robbie screwdriver! And hold the light steady” is like half my experiences with my dad. :-D Such a red-foreman.
in america everything must be named after a company
also isn’t it Robertson?
Robertson
Also the 6 lobe or whatever it’s called in the diagram is usually called a torx.
Robinson ftw though.
Robertson
Hahaha. Thanks, I didn’t even notice. Damn autocorrect.
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.
Now I want to see a ‘how it’s made’.
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.
They missed one
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
And if you lack the screwdriver. So long as the head is not the flat style and you have room. Angle grinder/dremel and everything turns into a flat head screw.
Slot screw head you mean. Flat head refers to a head with a shape designed to go into a countersunk hole.
…no it doesn’t. Flat head screwdriver. The head type is called a countersink or self-setting.
um no, that’s wrong.
You can type “flat head fastener” into google and it will explain to you that you are incorrect. Perhaps you don’t have much experience purchasing fasteners?
The person I replied to edited their comment to correct it.
Translation error
This guide is trash, they don’t even know the proper names.
“Square”? “SQUARE”??!! Excuse me, we fought a patent war over Robertson drive, and WE FUCKING WON.
Came here to say this
And “hexagon” is allan key.
Screw drive arguments are my absolute favorite, thank you OP for posting such divisive content!
Same - this will easily be my favorite post of the day, and it’s still early.
RIP
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
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
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.
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.
