Abstract

A new and improved thread rolling die, for forming a new and improved threaded fastener, comprises a plurality of first, primary thread rolling die threads, and a plurality of sets of second, auxiliary thread rolling die threads alternatively interposed between successive threads of the first, primary thread rolling die threads, so as to render the manufacturing process more cost effective by reducing the the number of revolutions, through which a blank member must be rotated in order to complete the formation of the thread leads upon the blank member, to be accordingly reduced which, in turn, permits the axial length of the thread rolling dies, and the thread rolling machines, to be reduced in size.
