Fun fact: Torx screwdrivers are compatible with Torx Plus screws, but Trox Plus screwdrivers are only compatible with Torx screws that are one size larger
I repair a lot of tech and I have never seen torx other than the standard, and security version. And security torx drivers are compatible with regular torx
There’s other types on cars
Torx plus is getting more common and you can use a torx bit on them still, and superior to torx IMO. I bet you’ve seen since but didn’t notice the difference. As a machine designer it’s my preference but I don’t often for cost
Torx plus ultra premium pro
I assume all those are proprietary temper resistant, tool for it will be expensive so not many tool shop gonna have it.
Not really. A solid set for security Torx is available for like $20 from reputable brands. Naturally, you can get higher quality sets and sets that add other security bits, but you still won’t land in an unacceptable price range even for private use, let alone a pro shop.
