ABSTRACT:
A die (20) particularly adapted for making a screw blank having a reduced diameter, offset or asymmetric section has a first die section (30) having a central bore (32), which mates with a second die section (50) having a smaller diameter and/or offset bore (52). A shaped end (57) of the smaller or offset bore (52), which forms the reduced diameter, offset or asymmetric section of a screw blank, is coated with a hard lubricating material. The method of manufacturing the die (20) involves making two first die sections (30), which are preferably identical, from a first die body (130), and two second die sections (50), which are also preferably identical and adapted to mate with the first die section (30), from a second die body (150).
