Designed with a left hand thread to assure greater locking power the thread winds in the direction opposite that in which the shaft of most assemblies rotate - a right hand direction. These nuts have become important in applications of high rotational speeds of racing vehicles and equipment drives. Also they serve immeasurably well in applications where a right hand thread and a left hand thread are applied to opposing ends of a shaft to allow for an ease in tightening and loosening power transmission assemblies in a more efficient manner.
