Here in Norway Torx is everywhere, almost all new screws and bits. It is like Torx is USB 3.0 and everything else is "legacy".
Torx just works. Never an issue (except smallest bit size TX10 can wear out quickly). I guess disadvantage is you need to have them in 4-5 sizes depending on screw size, like Hex, but that is easily worth it.
The smallest Torx size is a T1 (or TX1, whatever)! This size is best described as "pray that you never have to use it". I think I did... once... or maybe that was just staring at the driver wondering what it's for. Still, we have 16 different Torx sizes around here. Sixteen!
Also, there's a thing called Torx Plus out there. You can buy Torx Plus screws and things will work out for you, but don't buy Torx Plus bits unless you know what you're doing. That said, if you do use Torx Plus bits with Torx Plus screws, it works really well.
Off the top of my head there's TORX / tamper resistant TORX, TORX Plus, tamper resistant TORX Plus, whatever the external/female variant is called. TR TORX simply has a pin in the middle of the head, but TR TORX+ has five lobes versus six.
TORX Plus has made its rounds on the automotive circuit. It's designed to be somewhat backwards compatible but it is a lot easier to damage the fastener with a normal TORX driver.
That side note problem surely ranks as the #1 downside of torx. The practical solution seems to lie in restricting torx sizes to a much smaller subset, e.g. jump right up to T25 if T10 isn't enough (I think some fields actually do this?). But if you have the full set of drivers you can still mess up, no doubt.
I wonder if the pin/hole tolerances of the "tamper proof" variants are tight enough to keep the slightly smaller out? Then it's not so much about keeping out people who don't own the right tools (gatekeeping) but about keeping out hands that happen to not hold the right tool at the moment, which is very well possible even if one should know better, and the right tool is available as well. You should never blame the user for a mistake that could have been prevented by better UI.
the secure/tamperproof torx are fine, actually;
sometimes all screws are T15, and during a repair one of them has become T20 (embiggen the hole and what not). Preventing user errors in such cases is important, indeed.
> Side note: mistakenly using a smaller torx driver demolishes both the screw head and the driver... and it usually fits well.
Ahh yes, I learned this the hard way. T20 bit for a T25 screw, for example. It might work for a few screws then all of a sudden the next one gets destroyed.
From an automotive point-of-view TORX like Allen / "inhex" suffers because you can get a bunch of crap in the head and make it easier to get a bad fit with your driver and damage the fastener head. External/female TORX is also problematic because, you guessed it, you can get all sorts of gunk in the splines.
Torx are readily available everywhere here. Even discounter chains like Aldi have seasonal offerings (toolset containing Torx screwdrivers). I think you mean Apple's special pentalobe design for the iPhone (maybe also macbooks now)
They all wear out eventually, if you use them - but much more slowly than Philips or posidrive. Even a chewed up torx bit will still usually do the job - but a chewed up cross is useless.
I'd _very_ lightly push back on that for a posidrive, but it has a lot of asterisks. IF you can keep enough pressure on a posi, I've not seen issues. but if you can't it's failure case approaches the dreaded Phillips. And "enough pressure" is in the range of 170lbs of dude pushing down for really difficult situations in my experience, so yeah, "*"s abound.
Fair! I'm speaking from a US perspective here for torx availability, and largely interacting with things I didn't get to decide the hardware on myself.
Oh in that case you're just very apparently 40 years behind?, there are kits sold in supermarkets in the US that carry Torx bits. They are not uncommon at all.
In addition to automotive it is all over appliances, electronics (eg hard drives), laptops, small electronic devices including smart phones.
The Husky toolkit I purchased from Home Depot 25 years ago included Torx bits.
I am actually stupefied that someone can differentiate Philips from Pozidrive but isn't aware you can pick up a Torx driver set from any Walmart or Harbor Freight.
Okay you can find the bits, but what about the screws? I was specifically looking for them a while back and turns out the vast majority of screws that I was finding at stores (home depot, lowes, various local places) were still phillips. The ones that were robertsons or torx were the wrong configuration (metal, size, head type, etc). I ended up buying some online instead.
Just to show some data, go to home depot page and look at the screws categorized by drive style: I'm seeing ~2600 phillips heads, ~500 star (which appears to be torx under a different name), 55 square, and 27 torx (under the torx name).

Home Depot / Lowes is at least 50% torx screws these days. They're impossible to miss. Not sure where you're looking, but I'm talking about the actual physical store.
Especially if you look at screws intended for decking/lumber, it'll be an even higher % than 50.
>> At the moment they're a hard bit for a layperson to find, regardless of their advantages
That was the original comment, that is all I responded to - which is just a completely ridiculous.
And if you work on cars, you'll encounter the fasteners all the time.
But there's a very popular construction screw sold at Home Depot, etc that uses a "star" bit. The overall fastener selection at Home Depot isn't amazing, never has been - they've never been much of a hardware store. Check Grainger or something.
The "use things I don't choose the hardware for" is the more relavent part. And I didn't mean the torx is actually hard to find in stores, rather that I don't see it much in the wild. I have torx bits I'd love to use more, but minus some small electronics I rarely run into the screws in the wild. Even electronics I see hex far more often. Like I said, just what I see in my activities
