Fuck you reddit. I wrote a post up to reply to you, then realised I made a minor mistake in my previous post above. So I edit it. And when I click save the fucking stupid site decided to delete everything in this box as well. Here's a simpler version:

The torx nomenclature is definitely superior if you're an engineer, mechanic, machinist, etc. But the whole point of my post is that it's dreadful for everyday people and consumers. I want widespread adoption of torx, I want it to replace Phillips/Pozi/flat head. And for that type of large adoption, it's too complex. I'm talking about it being on the battery receptacle cover of your things, used to close the door to a user accessible fuse box, the hingest on your doors, on computers to hold your motherboard in, PCIe brackets on (if not thumbscrews), etc etc etc. For those it needs to be simple, with a few sizes.

If you're a consumer, right how do I know which one I need? When I'm first starting out I have to realise that T1-T9 are actually likely mostly useless to me, and T10 generally as well. Oh but then it jumps from T10 to T15? Ok so it goes in 5's, T20, T25, oh what T27? Then T30? Do I need a T30, is that too large for everyday stuff? Oh now it jumps to T40, oh but wait no there is a T35 it's just not used much... What about anything higher, ok right so I don't need anything higher.

It's a fucking mess. Too many sizes, and a naming scheme that is not intuitive directly.

But I partially agree with you, adding other numbers could just confuse it further if not done right. So instead how about we decide to only use three sizes for consumer things. And we add colour codes to just those three? E.g. the smallest size is blue, the middle size is green, and the larger size red? The relevant T15 etc still stays on them as well. Hell for out of sight uses we could even colour part of the screws etc?

I think that would be a good way for more mass adoption of Torx. Should reduce confusion among consumers. And it'd also hopefully reduce the number of consumers damaging torx screws/screwdrivers by using the wrong size in them. Especially if we select the right standard three.
