27559-25 PACK Jam lock nut chrome, 5/8-18 - 25 pack

These 5/8-18 jam lock nuts by Gardner-Westcott feature a brilliant chrome finish, designed for use on Harley-Davidson motorcycles where large, fine-thread fasteners are required. The jam nut profile is thinner than a standard nut, making it ideal for locking applications or for use in tight spaces where a full-sized nut cannot be accommodated. The chrome plating provides a durable, mirror-like finish that resists the elements and maintains its shine over time. Gardner-Westcott hardware is specifically engineered for American motorcycles, ensuring a perfect fit and professional results for every project. Sold in packs of 25.
