Abstract

A self-locking screw-threaded bolt comprises a shank with screw threads 16 thereon and an elongated recess formed in one side of the shank and constituted by a number of aligned notches in adjacent screw threads 16 the base 24 of the notches being disposed slightly above the roots of the screw threads so as not to weaken the shank, the notches comprising an inner portion 22 with inclined side walls and tangs 28 positioned below the crests of the screw threads and an outer portion 30, a strip 20 of plasties material being disposed in the notches and held in place by the tangs 28, the outer surface of the strip 20 conforming generally to the shape of the screw threads 16 and overlying adjacent portions of the screw threads on either side of the notches.
