Self-locking Nut

There are no thread interruptions or pitch errors to react unfavourably or to induce galling on the bolt threads. The two locking elements utilize most of the collar portion of the nut and the threads that come within its depth. The elliptical form of the locking collar with its distribution over wide areas of the locking pressure, ensures a high fatigue life with necessary flexibility to give consistent performance and dependability in service. These locking elements are designed to create gradually increasing areas of pressure and friction on the bolt threads.
