    Abstract: A self-retained bolt assembly including a bolt having a circumferentially compressible plastic ring carried in a groove at or adjacent the thread runout. The ring compresses as the bolt is inserted into or withdrawn from a workpiece. With the bolt installed in an aperture in a workpiece, with the ring having been passed completely through the workpiece, the ring diameter is greater than the diameter of the aperture, thereby holding the bolt in the workpiece even in the absence of a nut turned onto the bolt.
