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.

Use torx all the time on not only building sites, but in machinery repair too.

There's only one type of torx and I think OP is winding us up :)

Edit - ha ha oh my fucking god. So it turns out the patent for torx expired in 1990. No change for us in Europe, we're still mostly using the original design.

Not so much for the yanks. Textron, the original patent holder, realised it'd be faaaar more profitable to "licence" slightly improved designs and try to phase out the original

Enjoy your torx my euro friends, and have a giggle at the seppos paying for a fucking screw head lol

Greed to the point of mental illness 😂

There isn't. There's Torx, Torx Plus, and Torx Paralobe. See here for more details: https://www.semblex.com/en/pdf-files/technology-files/torx-paralobe-pdf/ . Plus there's also the ttap and tamper-resistant variants shown in the meme.

As other people have mentioned, Torx screwdrivers are forwards compatible with Torx Plus and Torx Paralobe. But the screwdrivers for the newer standards are not backwards compatible with older screws.

Similarly, Tamper-Resistant Torx screwdrivers can be used on regular Torx screws. But Tamper-Resistant Torx Plus screwdrivers cannot be used on regular Torx Plus screws -- it's a completely different shape!

If you're in a professional setting where you order high-quality screws and drivers in bulk directly from a manufacturer, I'd imagine that this isn't much of an issue. But if you're a hobbyist or just need to repair something in a domestic setting, the three different torx variants plus the other non-torx hexalobular screws (WA drive, Polydrive, T-Star Plus) can cause quite a bit of confusion. Anecdotally, I have a set of what I thought were really low-quality Torx bits. Turns out, they're actually good-quality Torx Plus bits that by design don't fit my Torx screws.

Yeah that's just what Big Torx wants us to think man

Put timing chains on a Ford v6 without a torx plus 55 and let us know how that went.

Security torx is actually very weak. If you don't have the security bit, you can break it with a flat head and turn it into a normal torx.
