1/4-20 STOVER LOCK NUT ZINC

Stover® lock nuts are one-piece hex nuts which derive their prevailing torque characteristics from controlled distortion of their top threads from their normal helical form to a more elliptical shape. Frequently used in farm machinery, plus in the automotive and metalworking industries, they can withstand severe vibration and shock loads. They are reusable and can withstand temperatures of up to 450°F.
