THREADED FASTENERS WITH FLEXIBLE FLANGE Abstract of the Disclosure A fastener such as a threaded nut, bolt or screw includes a body portion with a bearing surface at the workpiece engaging end defined at least in part by a flange. Segments of the bearing surface defined by the flange are flexible and resilient and other segments are rendered rigid by brace structure associated with the body portion of the fastener. In one embodiment, upon tightening of the fastener against a workpiece or other element, deflection of the resilient segments provides a spring action to compensate for developed looseness or loss of tension. In another embodiment, locking teeth project from the bearing surface in the resilient segments of the flange located between the rigid segments.
