The Cleveloc nut is a low cost one-piece self-locking nut with superior locking and re-usability characteristics. The locking collar is an integral part of the nut and is formed into a geometrically developed ellipse. This provides two locking elements of consistently uniform shape and thread contour which permit the bolt threads to engage smoothly during assembly.
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.
Further tightening forces the locking elements to engage more fully with the bolt threads and this increasing resistance to the entry of the bolt brings the full length of the nut threads into close contact with the working faces of the bolt threads. Further friction is created and both forces combine to give a smooth, progressive and increasing self-locking action.
