Abstract
A method of thread rolling a cylindrical sintered P/M blank is provided comprising, forming a sintered cylindrical powder metal (P/M) blank of density ranging from about 75% to 92% of the actual density of said metal blank having a selected diameter larger than the final pitch diameter of a predetermined roll threaded product produced therefrom and not substantially exceeding the outside diameter of said predetermined roll threaded product. The P/M blank diameter selected is substantially inversely related to the density of the blank, the P/M diameter selected being correlated to produce a substantially full thread. The sintered P/M blank is then thread rolled using a threading die corresponding to the gage of the predetermined roll threaded product to be produced.
