Speaking of tamper-proof screws, does anyone know the
name for the
ones that need a triangular-tip bit/driver? It's not a tri-wing, since
it doesn't have "wings". Just a triangular hole in the head.
Lara tools just calls them triangular resess.
I've got square bits. I think there's a name for those, but I've
forgotten it.
In Canada they call those Robertson bits. They use them a lot more than we do in the US.
The last time I was up there they were using them for dry wall screws, installing
electrical boxs in houses, etc.
I've also seen some screw heads that have three
tiny round holes, arranged
in a triangular pattern.
I've never seen those or the tools to R/R them (and I have a BOX full of bits).
I'm guessing that they're proprietary to one company.
