Abstract
A locking thread design which may be incorporated in various types of male and female threaded elements, for example, a bolt and nut, or a bolt and casting, forging or similar member having a threaded bore therein. The thread design is of the reversed buttress type and is free running until a predetermined magnitude of loading is applied thereto, at which time the locking action of the thread occurs so as to prevent relative lateral movement between the nut and bolt and hence positively resist loosening thereof under vibration and similar adverse operating conditions.
