Learning how to repair screws was one of the more useful parts of my education as a machinist. It's tedious but if you do it right, even the worst buggered up screw can be made to look and act like the screw's never seen a blade before. Peening the top flats back into shape is the most tedious part. I use a 4oz. brass mallet and a hard steel punch set that goes all the way from a 1/2" flat down to a 1/8" radius ball. To do it right, get a variety of jeweler's files - thicknesses of flat-smooth file from paper-thin up to 1/4" - leave the lathe bastard in the drawer, please; and no half-rounds! Cold blue, torch blue, blackening, oil smudge... finish depends on what looks good or is right for factory finish.In my experience, the better analogy would be using Allen wrenches to remove Torx screws.
I've damaged screw heads with un-modified, but "properly sized" craftsman screwdrivers.
I've also modified screwdrivers with grinders and files to fit screw heads properly, with great success.
One thing is for sure, it was worth my money to get an inexpensive gun screwdriver set with replaceable bits.
I hate following behind other people's work that have damaged screw heads, and now I have to figure out how to get that screw out. Adds money and time on a repair job at work. Which the boss likes the money, but frustrates me greatly.
