SPECIFICATIONS
An all-metal, one-piece Hex nut with a flange on the bottom side. The fastener derives its prevailing torque characteristics from controlled distortion of its top threads from their normal helical form to a more elliptical shape. Prevailing torque locknuts are one piece. The prevailing torque Hex nuts feature a conical top and a flat bottom bearing surface with chamfered corners. The locking action, created by distortion of their top threads, is said to resist loosening caused by shock, vibration and other dynamic forces.
