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 use Robertson screws all the time. I have yet to have
one strip when removing them. They come in at least 3
sizes and the screwdrivers are color coded according to
size. Black, Red,and Green. Can't remember the
dimensions. Many manufacturers are now supplying them
in dual Roberson, blade form.
