Upgrade & Restore Your Tire Changer's Mechanical Rigidity

The 5/16"-18" Lock Nut (Coats 8000525) is a direct-replacement mechanical fastener engineered for the foot pedal linkage and pivot assemblies of professional tire changers. It features a high-tensile steel body and a prevailing-torque nylon insert to resist backing off under constant mechanical vibrations and operational pedal shocks.

Regular maintenance and timely replacement of worn lock nuts are critical to protecting your pedal links and cylinders from mechanical play and keeping your machine operating smoothly.
