ABSTRACT:
A locking fastener such as a threaded nut, bolt or screw includes a body portion with a flange at the workpiece engaging end defining a bearing surface. Segments of the flange are rendered rigid by brace structure associated with the body portion of the fastener. Locking teeth project from the bearing surface in resilient segments of the flange located between the rigid segments. Upon tightening of the fastener against a workpiece, substantial clamp loads are imposed by the rigid flange segments while engagement of the teeth with the workpiece causes axial deflection of the resilient segments so that loss of clamp load and decrease in release torque due to tooth embedment is prevented.
