  • Load-relief washer assembly for threaded fasteners
    Patent number: 8579572
    Abstract: A load relief washer assembly for threaded fasteners comprises a lower washer piece, an upper washer piece, a plurality of complementary stepped features which further comprise the mating surfaces of the lower washer and the upper washer, such that sufficient rotation of the upper body relative to the lower body aligns the complementary stepped features allowing the upper body and the lower body to move toward each other, thereby reducing the overall height of the load relief washer assembly.

  • Low Torque Tension Relief System for Threaded Fasteners
    Publication number: 20130189047
    Abstract: A low torque tension relief system for threaded fasteners comprises an inner body with two sloped surfaces, upper and lower wedges which convert longitudinal movement of the inner body to a dimension change in the transverse direction, an outer body which acts to inhibit said movements, and a restraining bolt which passes through the outer body and engages the inner body thereby anchoring said inner body with said outer body and selectively restricting or promoting relative movement of said inner body compared to said outer body.

  • Hydraulically Activated Tension Relief System for Threaded Fasteners
    Publication number: 20120180280
    Abstract: A tension relief system for threaded fasteners comprises a main body housing a piston for generating a clamping load, seals to maintain the hydraulic pressure within the pressure chamber, an external pressure port extending through the body to the pressure chamber and adapted to be connected to an external pressure source, a connector on which the main body may be mounted, and a spring which may be compressed through the relative motion of the piston and the connector.
