Default Re: What is this for?

It always bothers me when I see several of the same bit in a set. I feel it means that the manufacturers expect them to wear out quickly.

There are several types of security screws that that set doesn't cover, and I've come across them in things appropriate to this forum :

System Zero

5 lobed torx-like thing

Triangular. I do not mean tri-wing, I mean a screw head with an triangular recess in it (as opposed to the hexagonal recess of an Allen screw). This is remarkably common in domestic appliances now, and remarkably hard to find the bit to undo it.
