Product description

This Shoulder Bolt is a specialized fastener used in Coats tire changer assemblies where a precise pivot or alignment point is required. Unlike standard bolts, the shoulder bolt features an unthreaded shank that provides a smooth, accurately sized bearing surface for rotating parts or linkage arms. These bolts are frequently found in the pedal assemblies, mounting arms, or bead loosener linkages of tire machines. Over years of operation, the shoulder can wear down or become scarred, leading to excessive "play" or slop in the machine's movements. Replacing a worn shoulder bolt restores the original mechanical tolerances, ensuring the machine operates with the precision intended by the manufacturer. It is constructed from high-tensile material to handle the shear forces and constant motion inherent in professional tire service equipment.
