ABSTRACT:
A self-locking fastener having a bearing surface comprising a plurality of sets of serrations arranged to penetrate a workpiece such that, while a resistance to the loosening of the fastener from the workpiece is created, the marring of the workpiece surface is minimized. Use of the fastener is particularly advantageous if the workpiece consists of soft materials such as cast-aluminum or non-heat treated carbon steels. Each set of serration, when viewed as a profile, includes a downwardly inclined surface, a relatively deeper serration and a relatively shallower intermediate serration. The intermediate serration controls the depth of the penetration into a workpiece.
