82573-25 PACK Ss int. lockwasher, 1/2 inch - 25 pack

These 1/2-inch internal tooth lockwashers are manufactured by Gardner-Westcott using stainless steel for maximum longevity. Unlike standard split washers, the internal teeth bite into both the fastener head and the mounting surface to provide exceptional grip against rotation and vibration. This 1/2-inch size is typically used for heavy-duty mounting points on Harley-Davidson motorcycles, such as major chassis components or large bracketry. The stainless steel finish ensures that the hardware remains free from corrosion over time, preserving both function and appearance. These internal lockwashers are sold in packs of 25.
