03557-25 PACK 9/16-18 locknut zinc - 25 pack

These 9/16 inch-18 fine-thread locknuts from Gardner-Westcott feature a zinc finish for reliable corrosion protection. The fine thread pitch allows for precise tensioning, while the locking mechanism ensures the nut remains seated despite the heavy vibration of a V-twin engine. These fasteners are commonly used in high-stress areas such as suspension pivots or specialized engine mounts where a secure, fine-thread connection is required. The zinc plating provides a long-lasting barrier against the elements for non-decorative applications. Gardner-Westcott hardware is engineered specifically for the demands of American motorcycles. These locknuts are sold in packs of 25.
