Rock Krawler universal jam nut with a 1-inch bore and 14 TPI left-hand thread provides a locking option where reverse-threaded fastening is required. Used as a secondary lock nut for adjustable linkages and threaded components, it secures settings and resists loosening in applications that need a left-hand thread for assembly or to counter standard-thread rotation.
