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

      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

        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

        There’s only one type of torx

        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.

      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.

      How do you feel about square drive? I’m no carpenter, just someone that’s done enough work around the house, but I’ve found that Torx are the best option but square is a close second (but I don’t think I’ve used them in any especially high torque situations, and they may fall short there).

          So square is a close second in terms of quality, while being vastly simpler and cheaper to manufacture. Seems to me like i’d prefer square.

          Also i’d be terrified of getting dirt in a torx screw, good luck cleaning it to make it usable again. Though i haven’t actually had this problem personally so it’s just a hunch

            I have torx all over my mountain bike that gets caked in dirt, a little bit of water and a pick gets them usable in seconds. I could argue that hex is superior to square but they’re both worse than torx so who really cares.

            Torx, hex, and square/Robertson all require broaching, generally with a rotary broach. The manufacturing process is basically identical, though the manufacturing of the machine tools varies slightly.

      Torx should be the default over Phillips for sure. Phillips is fine for shit like access panels or screw terminals. Slotted is useless for anything but the adjustment on pots and thermostats. Robertson is just a proto-torx. Everything else either exists to make someone money or is a bolt

          Phillips strips way, way easier than Torx. Stripping generally happens when a screwdriver cams out, or pops out of the screw. Here are some excerpts from Wikipedia of Torx vs Phillips.

          The hexalobular socket screw drive, often referred to by the original proprietary brand name Torx ( /ˈtɔːrks/) or by the alternative generic name star drive, uses a star-shaped recess in the fastener with six rounded points. It was designed to permit increased torque transfer from the driver to the bit compared to other drive systems. The drive was developed in 1967[44] by Camcar Textron.[45] Torx is very popular in the automotive and electronics industries because of resistance to cam out, and extended bit life, as well as reduced operator fatigue by minimizing the need to bear down on the drive tool to prevent cam out.

          And Philips on the other hand:

          The Phillips screwdriver design has a tendency to cam out during operation due to angled contact surfaces which create an axial force pushing the driver out of the recess as torque is applied. Despite popular belief,[2] there is no clear evidence that this was a deliberate design feature. When the original patent application was filed in 1933, the inventors described the key objectives as providing a screw head recess that (a) may be produced by a simple punching operation and which (b) is adapted for firm engagement with a driving tool with “no tendency of the driver to cam out”.

          I’m not sure about Allen. It doesn’t cam out very much, but it does still strip a lot easier than Torx. Probably due to the smaller contact points.

            Well said.

            And with the hex/Allen, it’s the small contact points as well as the smaller volume of material that needs to be deformed or removed before slippage can occur, as well as the angle of force on the contact point.

            With a hex, the contact point and direction are such that the tool is effectively trying to scrape off material at an angle, and if/when it succeeds even a little bit, it’s now much more prone to fail.

            With a Torx, the contact area might still be small, but it’s being applied to the lobe in a more perpendicular direction, so rather than a scraping failure, it’s more of a force that is pushing directly against steel instead of scraping. Not that it can’t fail, but the route to failure is significantly less likely.

          Yeah, it was made with torque in mind (like, it’s in the name lol). For smaller screws using an impact, you can expect to break the screw before you strip the torx on top. And by smaller I don’t mean tiny, more like M4, M5

    I have to admit that each time I saw a torx security screw on a case I had to open (looking at you, Compaq) this made me so angry that I used to punch the middle pin away with a flathead screwdriver, and replace the screw with a regular one later. This was in those past times I did not have a fuckton of assorted torx bits in a gigantic case…

          Yes I’ve always referred to them as Compaq screws but mainly because I personally saw them on Compaq first. I think HP bought Compaq at some point and that might explain why they are used on both brands. Don’t know which brand started using them first.

          I would have rather had they just used Phillips screws but as far as weird screwheads go these aren’t too bad.

          At least the good thing about them is the threads are standard and they can be replaced with a Phillipshead case screw just as well.

    Useful tip: with security torx screws, with the little nub in the centre, if you get a small flathead screwdriver to jam in there and wiggle a bit, that centre bit will snap off without much difficulty.
    You should be able to use a regular Torx screwdriver bit after that.

              It’s probably because of the impact driver. The bit seats back into the bottom of the slot between every impact. This doesn’t happen with normal drivers.

      they’re pretty good but semi liable to stripping due to lower surface area, as long as you use the right tool, and a quality one, you’ll be fine though.

          small screws in general are just easy to strip. Small torx is also liable to breaking a driver, like most small screws and drivers.

          Torx though, i’ve never had strip out once, even doing construction with them. Phillips on the other hand, they kill screws constantly, and the bits themselves get all chewed up causing all kinds of problems. Torx bits still look fine though.

          Torx aren’t exactly tapered, so they much less of a problem with stripping, compared to any tapered design, because tapered designs have issues with backing off.

            Hexes are very sturdy. I ride mountain bikes and for some reason brake rotors are secured with Torx while all other screws are hexes. Torx on rotors are usually tightened to 4-6Nm and they are single use 99% of the time. At the same time there are plenty of hexes of the same size which are tightened to 8-10Nm and there are zero issues.

            Torx are fucking useless. And don’t get me started on tiny Torxes in laptops…

              I could see hex performing better on a softer material. That or you’re doing something goofy. I’d be surprised if torx were stripping at that low of a torque rating, unless ur using hex drivers on them or something.

                Fasteners are standard from rotor manufacturers. I have no clue what they’re made out of. But in 30 years of cycling I’ve never had a single Torx which would last more than one cycle of screw in screw out.

                  that’s bizarre. Torx are commonly used in construction with impact drivers, and in vehicles as well. Very rarely are they ever problematic, and that’s with quite significant shock loading as well as torque application in the case of construction, i would imagine more than in a bike, but i wouldn’t be able to say off the top of my head, though they might be bigger standard head sizes, so that could be it.

                  Regardless, begs the question why hex screws aren’t in construction, those should be simpler and easier to produce.
