QA1 Jam Nuts
Maintaining critical adjustments in areas, such as suspension alignment and throttle linkages, often depends on jam nuts. QA1 jam nuts are made from high-carbon steel, are zinc plated for corrosion resistance, and meet ANSI B18.2.2-1972 standards. The jam nuts with left hand threads have a circumferential groove for easy identification.
