Since when is a Torx bit "metric" in the sense that it's not justified for NA? Torx is extremely common and pretty much the standard for onstruction screws these days.
I'm pretty sure they are. Of course, they are not marketed that way, but IIRC, they fit inside of the appropriate size metric hex. (internal and external) I'm not entirely sure about the point of the external though? Why do those even exist? For that matter, why the internal either?
My first experience with Torx was with hood and door hinges on Jeeps. This was in the late 70s/early 80s. Stupidly, they were painted
after assembly. There was no way to disassemble them, without damaging something. The sockets always got chewed up. (the paint anyway) Drivers/tips were actually hard to get back then. It was somewhat tamper-resistant, long before the intentionally made style, they make now.
I was a little concerned about the future availability of the 100mm tips, when I bought the set. It was a Limited Edition, and that sometimes has an effect on that kind of thing. Sometimes they are just a bunch of items that are sold as individual pieces, combined and discounted. Other times, not so much.
The insert trays? I'm not so sure about those. It's not
really an official product, more like "packaging". It would only be available internally, as an assembly line item. So, I get it that they wouldn't want to retail them.
The bits though? I don't get that. They are a proprietary fitment, that I would imagine they defend with the patent?
Even if they wouldn't offer them in a real retail situation, maybe as an EKat item? (Replacement/repair part)
