Zusammenfassung:	A locking bolt assembly that prevents the release of loose parts in the event of bolt failure. A bolt having a head and threaded main body portion is provided with a central bore through the head and main body portion. The central bore has a necked down area adjacent the end of the main body portion away from the head. A plurality of slots along the end of the main body portion in communication with the central bore form bolt fingers around the necked down area. A plunger slidably received in the central bore places radial pressure at the necked down area to expand the bolt fingers outwardly and lock the bolt in its installed position without changing the preload of the installed bolt. The plunger is retained in its bolt locking position and prevents the release of loose parts in the event of bolt failure.
