18548-25 PACK Locknut (flexlock) 5/16-18 - 25 pack

This Gardner-Westcott flexlock nut features a 5/16-18 thread pitch, ideal for securing various components on a Harley-Davidson where vibration is a constant factor. The all-metal locking mechanism uses a slotted top to provide a mechanical grip on the bolt threads, ensuring the nut stays in place without the need for chemical lockers or plastic inserts. The chrome finish ensures these fasteners blend perfectly with other polished or plated parts on the motorcycle. Gardner-Westcott fasteners are manufactured to exacting standards, offering the durability required for V-twin applications. These nuts are sold in packs of 25, making them a practical choice for workshops and custom builders who require uniform hardware.
