A locking fastener in which coacting ramp surfaces are employed to generate wedging forces in response to backing-off movement of the associated nut which urges the nut into tighter engagement with the associated bolt and workpiece and in which spring means are provided which are compressed during the tightening operation and which bias the ramp surfaces for movement in a direction to augment the locking action of the fastener.
