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.
I've got square bits. I think there's a name for those, but I've
forgotten it.
I've also seen some screw heads that have three tiny round holes, arranged
in a triangular pattern.
