17548-25 PACK Nylon locknuts 5/16 inch-18 - 25 pack

These Gardner-Westcott 5/16-18 nylon locknuts feature a brilliant chrome finish, combining functional security with a custom look. The integrated nylon insert grips the bolt threads to prevent backing off under vibration, while the chrome plating ensures the hardware blends seamlessly with other polished or plated components on a Harley-Davidson. These are typically used for mounting footpegs, exhaust brackets, or other visible chassis components where both aesthetics and reliability are paramount. The 5/16-18 thread size is a standard American fastener found throughout the motorcycle. These are sold in packs of 25.
