ABSTRACT:
A fastener assembly, having a threaded male and female member, is disclosed. One of the members has substantially conventional threads and the other member has two threaded portions rotationally offset relative to one another. Direction of the offset determines whether a compressive or tensile preload force occurs in the assembled fastener. Magnitude of the preload force is controlled by the extent of the offset. One of the threaded portions includes at least two, preferably about four, tapered threads which permit gradual distribution of the preload force and thereby prevent plastic deformation of the threads. The assembled fastener is substantially vibration proof, and, due to the well controlled permanent preload force, is highly fatigue resistant.
