Torx kinda requires it be made of a decent alloy, it was developed to handle situations where you really really need torque. Handling more force than anything else was the guiding principle of its design.

Hence you find it in places such as bicycle disc brake rotor mounts.

Hex could even be A tier except...

• 10 million metric sizes
• 10 million imperial sizes
• heads get full of rust or dirt
• note that this makes it even harder to tell which damn size they are
• usually mild steel so they strip, especially when it turns out you're using imperial in metric and vice versa

Too many years of wrenching on old equipment has soured me on all except for the good old fashioned hex bolt (S tier) and Robertson (A tier).

Even slotted beats most of these if the steel is decent, scrape out the rust and whack it with an impact screwdriver. I've turned many torx and hex in particular into slotted over the years.

I could be talked into bumping Hex up to B, I just want it between Phillips and Robertson.

I don't have any experience with Pozi screws in the US, but doing a quick search they look like a solid upgrade over Phillips, so I'm guessing I would agree if I actually used them.

Yeah, combo is where it's at in terms of field serviceability. I pretty much always have a flathead on hand, but very rarely have a torx but set, Allen key, or Robertson close at hand if I'm in the field.

any screw is a flathead screw if you have a dremel

I've used them very rarely, but I've never had one strip unlike everything beneath it so I can't complain.

Posidriv can bugger off too.

When you look at a Robertson, or a JIS or even a Phillips you just use a JIS or Robertson and you’re fine. If it is posidriv, you must use posidriv and you can’t use posidriv with a conventional Robertson/Phillips/JIS. The only way you can tell the difference is by a teeny-tiny little dot on the screwhead or some extra minuscule fins on the driver. If you do t have your glasses, or aren’t aware, you will damage the screw and your driver.

Hex and Torx are OK for certain things where you don’t want an ignorant pleb to gain access. Security Hex and Security Torx are OK where you don’t want an ignorant pleb in denial of their ignorance to gain access.

All those other drivers, Triwing, Pentalobe, variants of Posidriv are just there to push proprietary applications and should not be used by anyone.

Applications exposed to corosion really should use external drive fasteners.

'cross-head' and 'flat-head' for me

Hey cool my grandfather was named witold. Probably had some strong opinions on screwdrivers too tbh.

Torx is the one true god
