This Gardner-Westcott jam nut features a 5/8-11 thread pitch and a thin-profile design, making it suitable for locking larger threaded components on a Harley-Davidson. Often used on heavy-duty linkages or custom axle setups, the jam nut acts as a secondary fastener to secure primary nuts or adjusters against vibration. The chrome finish provides a polished look that integrates seamlessly with other brightwork on the motorcycle. Gardner-Westcott fasteners are a staple in the custom motorcycle industry, known for their precise manufacturing and resistance to the elements. These nuts are sold in packs of 25, ensuring a uniform look across multiple mounting points on your machine.
