When you find an engraved screw head that has been abused my advice is to send it to an engraver and let him (or her) fix it.

One time I bought a Joseph Tonks of Boston shotgun which had a broken off hammer screw. I got the threaded part out and made a new screw. I then sent the other screw and the one I made to an engraver. When I got it back I sent it to the late Dr Oscar Gaddy who then nickle plated the screw and then remove some nickle to match the other screw. There are no short cuts to doing it right. When all was said and done that was one darn expensive screw ;-).
