Abstract

1,268,416. Rolling threads. J. H. STOVER III. 18 Aug., 1969 [24 Oct., 1968], No. 41176/69. Heading B3M. [Also in Division F2] A self-locking bolt, stud or set screw is formed by rolling an unthreaded blank having a bore in its leading end between a pair of dies 12, 13 (Fig. 1) opposed parts of the thread on the blank being indented to provide a portion of the blank with an elliptical cross-section. The blank is indented by inserts 20 and 21 carried in the dies, each insert being held in a cylindrical bore by a screw 23. The threading grooves on each insert, Fig. 9, protrude outwardly to deform the blank in the region of a central bore provided in the end of the blank. The main threading grooves of each die are relieved in the region 12d following the insert. The bore in the blank has a length of 1D and a diameter of 0À35 to 0À5 D, where D is the outer diameter of the rolled thread. The diameter of the major axis of the elliptical cross-section is about 1À03 D.
