Abstract

1394027 Lock nuts and bolts STANDARD PRESSED STEEL CO 22 Feb 1973 [22 Feb 1972] 8710/73 Heading F2H A self-locking nut or the head of a self-locking bolt has on its bearing face an array of substantially radial teeth 20 of saw-tooth crosssection the crests 22 of which are radiused or formed as flats 30 to limit penetration of the teeth into a workpiece when the nut or bolt is engaged with the workpiece. The crests 22 of the teeth may define a radial plane or a frustoconical surface. The teeth may be surrounded by a smooth annular rim 18 which engages the surface of the workpiece to contain stress concentrations caused by the action of the teeth 20 within its circle. The rim 18 may form a continuation of the surface defined by the tooth crests (Figs. 4, 6, 8, 10, not shown) or may be slightly inclined to that surface (Figs. 7, 11, not shown) or may be convexly curved in radial section, being tangential to the crests of the teeth where it meets them (Figs. 5, 9, not shown). The roots 24 of the teeth may be linear or curved when viewed in radial section. Reference has been directed by the Comptroller to Specifications 1,268,862 and 1,326,380.
