If it ain’t broke…
You’d think that they would have switched to Pozidriv.
TIL
Why? Torx is better in every way. If you are going to change, why half ass it to Phillips 2.0
Backwards compatibility
Pozidriv is intentionally not backwards compatible, and one of the biggest problems it has is looking enough like Phillips that people assume it must be compatible, use a mismatched screw and driver, and strip a head.
Which is why it sucks. I go to work and I see a cross cut, I’m going to use my Phillips head of appropriate size to pull it out or put it in. Does pozidrive have any indication it’s not Phillips? I’ve honestly never seen one. I might be working on brand new stuff or 60 year old stuff.
I don’t have any pozidrive bits but I have two sets of long torx, some double sided torx for my hand driver, and a bunch of little torx bits in my bag to hand out to the kid that came to his first day of work with nothing but a #2 Phillips.
Yes, the head is visually distinctive from Phillips, with four smaller cuts in between the main ones.
Good to know if I ever see one.
I think it’s pretty likely that you’ve seen loads and never known they were different. The difference is small enough that you wouldn’t realise it was significant until you were told:
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.
(@Dan not shitting on you, i just really hate Phillips)
Next logical increment… Gotta say ain’t nothing logical about Phillips/posidrive bullshit,
Robertson drive was around when Henry Ford decided to use Phillips on his cars. Robertson was more expensive to licence the patents(Phillips was cheap cause people thought it was shit)
God damned Nazis fucking everything up(Ford was a Nazi(ish) and a real piece of shit). Maximizing profits over everything else screws everything up as we are seeing right now, but sometimes it doesn’t just fuck up the here and now, but like Phillips, it just keeps fucking everything up for more than 100 years.
“Let’s make a drive that has an angle to it so that it will strip out super easily and destroy the fastener(don’t tell me Phillips is great because it limits torque, it doesn’t without destroying the head so bad you might not be able to remove it)” said no good engineer ever.
I thought we got over Bricks and Screws years ago
A 500+ million dollar budget and you can’t even take a proper picture.
What’s wrong with the picture?
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?
They strip like a mf.
If you have ever used torx once in your life you can’t say that Philip is great anymore.
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 have used torx in weird angle with less issue than Phillips . My heart is fully sold to torx and Allen keys ❤️
Angled screws only work halfway well with Pozidriv
or Torx, standard Phillips 
slip too.Btw, why is Torq-set
or Tri-wing 
so uncommon? They seem the best mechanically.Edit: no way to change image size in markdown?
Efitedit: why does this exist?

Because it’s a fucking stupid design! Fuck Phillips, long live Robertson!
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.
A good balled hex driver is such a joy to use. Somewhat align it with the screw, and you can use it at weird angle.
I prefer to only use them when I can’t get alignment. They’re far more likely to round out the head in my experience, but they have their uses.
Maybe I didn’t use them enough yet, but I bought some Wiha balled hex driver and I haven’t stripped a screw yet, and I use cheap screws.
I also had to dismantle my 3d printer hot end with a lot of weirdly placed screws and it wasn’t even an issue.
Fair enough, I’m talking about big H5 construction screws and impact drivers, so a different use case maybe. Also it turns out when ARRMA uses too much threadlock on their axle set screws you can strip them really easily, and I needed more expensive special hex drivers with tight tolerances to work with them.
I thought it was going to say “IG-88 was a dildo.”
He certainly looks like one
Um, actually, those are rigid kal’dron adjustment pins used to correct focus crystal orientation.
Huh always thought that was a self sealing stem bolt
Wrong universe
See that whooshing over your head its the Clear Air Turbulence.
Where do you think we got it from?
Bet it’s an inch screw too
Could be JIS.
Thank you!
Its all fun and games until the Canadians show up.
As an American, we made a mistake in not adopting those. Torx or whatever isn’t even as good.
Oh okay. So just like with everything else we’ve failed to do
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.
Hex already fit that niche.
Torx was just so they could make wood screws that weren’t Robertson and it bled out from there.
Torx bits are waaaay stronger than hex. Like double the surface area and tapered to work when corroded.
My 30 year old VW axles with hex bolts were a nightmare. The new ones are all Torx or 12pt.
I ended to driving an oversized Torx but into the nearly stripped hex bolts to finally remove them.
This guy mechanics
Indeed torx is so good because it attempts to maximize the surface where pressure is applied to. This is good on smaller sized bolts that are more prone to being rounded, but especially amazing when removing bolts that may have been exposed and potentially corroded
Hex was for that before.
Yeah, hex is very nice but torx is improvement over it.
I have not checked on it, but I’m like 97.25% sure wood screws jumped from Philips to torx however because of corrosion resistance. Hex is very easy to round already as is on smaller sizes, but even more so if the head is exposed to elements and corroded. Of course material matters a lot, but even stainless corrodes over time.
Torx has to be very, very bad condition for it to round, it’s more likely for the screw to snap
Sorry for drunk rambling but I really like bolts. And bearings for what it’s worth
Curious how “really like bolts. And bearings!” is working out on your Tindr profile?
Luckily I’ve never had a tinder profile. And my wife liked my nuts so we’re good
Never had or seen a stripped Robertson, they are robust AF. Don’t ask me the physics. (They go deep into the screw head because of the simple shape, maybe that has part of it. And they are tapered, it’s not just a square, so they manage to grip the bit like a mofo. You don’t cam out of a Robertson.)
I’ve snapped so many Robertson bits in my life. Screws are fine.
1 5/8" cement board screws
They used to be Robertson. They switched to Torx.
Night and day difference
Like you said, they do grip like a mofo, and with an impact driver, the bits snap.
I tried dozens of different brands of bits. Even paid top dollar for special Milwaukee ones.
I was at a point where I had to pre-drill and counter sink the screws because I was breaking too many bits.
I could probably drive a torx head one through a board
Yeah boi
Germany has entered the chat.
I’ve stripped more internal hex than all other types combined
The internal hex on sway bar end links are useless after any time in the salt. Last time I had to remove them I went straight to the angle grinder and ordered a new pair. Didn’t even attempt it.
We have to go deeper.
Ironically enough other standards appeared because of the need of more torque.
That’s the joke
Turns out the laws of physics and geometry are the same everywhere.
Even in fictional universes that have wizards in space with swords made of light?
Yes!
Then why would they end up with philips instead of torx?
They get sick pleasure from inflicting stupid fastener design on their users?
Hey, if it works it works.
It works, but badly. All my homies hate cam-out and love torx.
It works great for it’s intended purpose which is torque limiting.
Well, limiting torque but killing itself and becoming extremely hard to remove is terrible design lol
Correct. The original patent makes no reference to any sort of cam out / torque limiting feature.
