Torx >
Robertson is top tier too
I find Torx unpleasant to work with.

For me, it’s how the key feels in the head. It doesn’t go in far enough that you can let the key just sit there on it’s own like with a hex head.

The flipside to that is when you’ve got a JIS driver and when you’re done it doesn’t want to let go of the screw. Very satisfying, possibly sexual.

That’s more of a tapping motion for me, but everyone has different needs and who am I to judge?
I guess it just depends on your tools, I prefer torx over hex because it feels much more solid and less likely to strip out if it’s a cheap screw, I worked on a product that had the outside screws there were supposed to look nice use these hex heads made of butter haha but the rest of the appliance used all torx of the same size head
Maybe, I only work with high tensile stuff and occasionally stainless, so I’ve never had issues with hex heads (that weren’t caused by misuse)
Me out here calling them “plus head” and “minus head” like a neanderthal
we call philips “cross” and flathead “slit”
‘cross-head’ and ‘flat-head’ for me
Then there’s german, with (technically) slit and cross-slit

Neanderthals were on to something then
omg I’ve found my people, you all have strong opinions on screw driver geometry
Torx and Robertson are the best.
I always know I’ve found my people when they have extremely strong beliefs on everyday household items. My favorite was a 3 week argument about electrical sockets on Reddit a few years ago
I fucking hate Phillips style so much.
Never tried JIS though, Robertson is where it’s at.

But not #1, or most of #2, in common stainless alloys. Even dry film lubed and drill tip is insufficient to prevent the torque from exceeding the (relatively low) yield strength, leading to stripped screws from standard driving in any wood denser than about G=0.45. There’s simply not enough contact area to prevent it.
Stainless fasteners are niche and require stainless tools, full-stop.
Most fasteners are not stainless.
require stainless tools
You really don’t want to use stainless tools as they will plastically deform. Roberson is just not that great for torque-transfer geometry; it’s advantages lie elsewhere.

They are made specifically for stainless fasteners.
You’ll frequently find them in the toolbags of aerospace professionals and industrial electricians and they are really the only folks that deal with a lot of stainless fasteners.
Bicycle and motorbike folks have lots of stainless hardware, too. And lots of time you’ll see folks blame JIS/Phillips on ruining their fasteners, but sometimes it’s just because they’re using toolsteel tools on stainless fasteners.
Pozidriv enters the chat
How does a positraction on a Plymouth work? It just does.
I wonder how many pozidriv screws have been stripped and a Phillips driver has gotten the blame.
I’m trying to understand what the top half of each diagram is

Screw this meme
Torx is superior in every single way.
Torx blows. Robertson’s where it’s at.
Robertson has the issue of when force is applied it is at angles that can easily damage the head and the tool or both.
In general I feel Robertson is excellent for low torque applications, but torx doesn’t have any of these issues.
Aww Jis

Not only is it self-centering like phillips and JIS (eg the reason they are used in so many line-assembled manufactured goods) but it’s has superior contact like a Robertson (square drive) or hex or torx.

Torx’s highest-in-class leverage without camming out gives it superiority in some applications (eg impact-rated deck screws), but if you had to choose one fastener head for everything, posidriv is it.
Torx is not self-centering, and therefore inappropriate for many tasks including anything not hand-assembled. It is also susceptible to stripping out after rusting.
Isn’t it proprietary?
The patent is expired and it now has ANSI and ISO standards.
That guy loves jis lol
It’s not about the depth, it’s all about the angle.
Sounds like someone is working with a small screwdriver, if you ask me.

Around the 16:05 mark. Im not a screw connoisseur but I remember this clip :)
