ABSTRACT:
A self-locking fastener for a threaded joint having an end portion with a plurality of teeth in an annular array arranged to indent a coacting surface of a workpiece, to resist loosening. The teeth have individual top bearing surfaces which comprise discontinuous sections of the end surface of the fastener body, the sections being flanked in opposite circumferential directions respectively by abruptly and gradually sloping side surfaces, enabling the fasteners to be turned in a tightening direction and resisting turning in a loosening direction. The top bearing surfaces spread the clamp load and limit indentation of the teeth into the coacting surface to an extent determined by the combined areas of the top bearing surfaces engaged with the coacting surface.
