03559 5/8-18 locknut zinc

This 5/8-18 zinc-plated locknut from Gardner-Westcott is a versatile fastener for many Harley-Davidson applications. It is commonly used as a rear axle nut on 1973 to 2002 Big Twin and Sportster models, as well as a front axle nut for late 1988 to 2002 Springer models. Sold in a pack of five, these nuts are essential for any well-stocked workshop. The zinc plating provides a durable finish that resists corrosion, while the locking design ensures the nut stays tight under the vibrations of the road. It serves as a reliable replacement for OEM 7994, providing the security you need for critical axle and chassis components during routine maintenance or a full custom build.
