Product description

This Grade 5 Hex Head Cap Screw, measuring 3/4 x 7-1/2, is one of the primary structural bolts used in heavy-duty Coats tire changers. It is typically found in the main pivot assemblies or as a central anchor for the bead breaker arm, where massive leverage and force are applied. Grade 5 steel is chosen for its excellent balance of strength and ductility, allowing it to withstand extreme pressure without becoming brittle. Over years of operation, these large bolts can experience fatigue or corrosion that compromises the stability of the entire machine. Installing a new, high-quality replacement ensures that the heavy mechanical arms of your tire changer remain safely and securely attached. This bolt is a critical part of maintaining the high-performance standards expected from your shop equipment.
