I feel like a + shaped screw head would be as standard as a pyramid if multiple civilizations had developed screws independently. It wouldn't be the last kind, but it would be there somewhere. Maybe even a long, long time ago.
This bugs me so much more than it should. Why do we have three different standards for + shaped screws? You know what doesn't have this problem? Flatheads. There's exactly one way to make a flathead screwdriver, and I won't be looking it up to make sure I'm right
I see that multiple people have replied, but unfortunately reading these comments would be a form of research so I must decline
I think a single slotted screw head would be more universal and easy. You just cut one line into the top of the screw head and your ready to go. A Philips head would need to be cut twice and once you did, you've weakened the head one degree more by removing more material
You clearly haven't had to screw a flathead screw.
Anyone that's dicked around with those little bastards starts hating life after about thirty seconds. A fastener I can screw in a without having to be perfectly in line with the shaft? Yes please! I don't care if it's a shitty Phillips screw, sign me up. I'd even take those goofy square Canadian screws. Hell, anything is better than flathead.
I challenge you to find a screw worse to use than a flathead screw.
Ohhh no... As a person who regularly builds random shit for film and television, the single slotted screw is the bane of my bloody existence. Some designers fucking love em for the aesthetic but the cam outs on them are terrible. Is it technically easier to produce? Yes, is it viable to use for construction purposes comparitively - fuck no. Every time you cam out ( lose traction on the screw) you risk accidentally damaging whatever medium you are screwing into.
Locally there is an insane institutional preference for the Robertson screw (which is basically a square) because it doesn't cam out much, drives in well and arguably resists stripping better than a Phillips... This is believed in so much that any screw not seen by the camera is a Robby (usually size 2) while anything that is perceived by the audience is a phillips or a single slot screw. Given a choice nobody wants to handle single slots and chances are good you only find them in period specific builds or when the designer is a psychopath.
Absolutely the only benefit to slot headed screws is how easy they are to make, which is why they're what a home machinist would make when creating his own fasteners, and why any aliens out there that use threaded fasteners have probably also tried and learned to hate them.
Most other shapes of driver aren't cut, they're stamped.
Torx is better than whatever this Canadian abomination is. You'd only put pressure on the corners in a realistic setting. These would get rounded so fast unless they are massive, like on some differentials or gearbox oil drains.
Officially, "flathead" refers to countersunk screws. Slotted screws are terrible for my purposes, but they actually do have 1 advantage. If they get mud or something caked up in the slot it's relatively easy to use a knife or some other pointy thing to clean it out. Guns and other things used in dirty environments often use slotted fasteners for that reason.
Right, field maintenance, especially when you don't have access to tools is a bit of an exception. Personally I think using take down pins for guns is the way to go for field maintenance anyway.
Torx for anything that needs to be torqued or used with power tools, Robertson (square) for anything intended to be used with hand tools or more finer work (a screwdriver)
Square (Robertson) and/or torx depending on application. Square should be for everyday things and torx should be for anything mechanical, yes I know there is a big gray area in the middle there, but flat head, phillips, and hex need to go.
I don't get the problem with flathead, for household applications it seems the most superior because I can use literally anything in my house to drive the screw (butter knife, credit card, a housekey)
plus almost every size of flathead screwdriver can fit in almost every size of flathead screw.
No offense, but you haven't unscrewed/screwed enough slot screws if you don't see why they're worse in every way. The criteria for a good screw isn't that you don't have to have the correct tool. The bits are $0.99!
I unscrew a single screw and whether it's a light switch or an electronic device, I'm already annoyed. Even if you use a flathead screwdriver that fits perfectly, it will un-center and slip out, whether you use a hand bit/screw driver or a drill.
You can use everything, but everything works badly. Even a fitting screwdriver will just randomly jump out after half a turn and scratch whatever you're working on.
It is a curious fact, and one to which no one knows quite how much importance to attach, that something like 85% of all known worlds in the Galaxy, be they primitive or highly advanced, have invented a drink called jynnan tonnyx, or gee-N'N-T'N-ix, or jinond-o-nicks, or any one of a thousand or more variations on the same phonetic theme. The drinks themselves are not the same, and vary between the Sivolvian 'chinanto/mnigs' which is ordinary water served at slightly above room temperature, and the Gagrakackan 'tzjin-anthony-ks' which kill cows at a hundred paces; and in fact the one common factor between all of them, beyond the fact that the names sound the same, is that they were all invented and named before the worlds concerned made contact with any other worlds.
What can be made of this fact? It exists in total isolation. As far as any theory of structural linguistics is concerned it is right off the graph, and yet it persists. Old structural linguists get very angry when young structural linguists go on about it. Young structural linguists get deeply excited about it and stay up late at night convinced that they are very close to something of profound importance, and end up becoming old structural linguists before their time, getting very angry with the young ones. Structural linguistics is a bitterly divided and unhappy discipline, and a large number of its practitioners spend too many nights drowning their problems in Ouisghian Zodahs.
Preventing cam-out with a Phillips screw is like learning the ways of the Force. It takes patience and skill, something the Empire’s rigid Torx would never understand.
Why wouldn't they? It's an efficient design, and aside from the whole force thing they seem to be working with the same physics that we are. Why wouldn't they invent philips head screws?
This is a bit of a pet peeve of mine - it's designed purely for automation. That's why it's tapered, to allow power tools to slip out before they break. That's good for automation in the *1930s (EDIT: I've realised that in a few years it will be the 30s again and maybe I shouldn't leave this so ambiguous in light of that), not so good for hand tools or any modern tool with a torque limiter.
You're much better off with hex or torx, or even the square driver, which is much more tolerant of imperfect handheld tool usage.
The only reason phillips is still used is because it's ubiquitous, it's very much a historical oddity. It's okay for many tasks but unfortunately the slipping out behaviour can destroy the screws very quickly.
I mean it's conceivable they'd come up with something similar, and it would be weird to expect a props department to find different screw heads just to be lore accurate.
Edit: Plus it's common today, which means from a prop design standpoint it communicates the idea that it's hand-built, because just about everyone has a phillips head screwdriver, so seeing it tells you it's something you can work on. I think that's the main reason it would be there. Jedi are supposed to make their own lightsabers.
Torx is cool and all but all the touted virtues such as less cam-out go out the window if you have to drive them in at wonky angles, like tight fitting spaces. If you gotta angle the driver it's not gonna seat well at all, apt to jump and wear out your bit. And if your only T20 rolls away and falls under a deck, yuck, 10mm problems.
Phillips has a place and that place is 'a wonky place to hold a power drill'. That said I'm a huge fan of square head because it's a happy medium between those two
I'm sure they have some kind of crazy riveting technology. Is she installing screws because she wants to be able to easily take apart her lightsaber if needed?
You're right - Torx is definitely a better option. I just mentioned Pozidriv because people seem to love Phillips head so much for whatever reason, so Pozidriv seems like a logical increment from there.
