Abstract

566,190. Making set-screws. NEWALL, A. P. July 17, 1943, No. 11650. [Class 83 (ii)] In the manufacture of socketed-head setscrews, a head is forged and/or machined on one end of a blank and at least a part of the shank is extruded or swaged to a reduced diameter and provided with a rolled thread, preferably by die rolls. A cylindrical socket is formed in the head which is then extruded or swaged to close the socket around a former of the shape required for the socket, and the head is heat treated in a manner to cause local internal hardening of the lateral walls of the socket.
