Abstract: A thread-rolling method as well as thread-rolling dies and method for manufacturing the dies. The shank on which the thread is rolled has a tapered free end region, and the dies which are used for rolling the thread are initially made up of a pair of individual sections having flat and inclined die faces with these sections subsequently joined to each other to form the complete die. The threads may be of lobular configuration, and during the rolling of the thread itself the lobes are simultaneously formed. The lobes for the threads are achieved directly from the thread-rolling dies by pressing across the ridges thereof tools which form in the ridges indentations having a predetermined pattern of distribution which will achieve the required distribution of the lobes on the thread which is rolled.

Abstract: A vibration-resistant, thread-forming screw. The screw has an elongated shank made of a solid, one-piece body and provided with an interior core portion which, in any plane normal to the shank axis, has a circular configuration. Integral with and projecting radially from this core portion are a plurality of lobes uniformly distributed circumferentially about the shank axis and extending along spirals which progress angularly about the shank axis in a direction opposite to the thread. Each lobe has, in the direction in which the screw is turned into a body, an elongated leading leg which progresses gradually away from the shank axis in the latter direction of turning and a relatively short trailing leg which returns abruptly toward the shank axis before joining the leading leg of the next lobe. A specially shaped die for forming the screw.
