235020 25PCK Internal Lockwashers 5 8

These internal lock washers from Midwest Acorn Nut Company are engineered to secure fasteners against the heavy vibrations typical of Harley-Davidson motorcycles. The internal teeth bite into the mating surfaces to create a reliable mechanical bond, preventing bolts from backing out over time. Each washer is finished with a bright chrome plating to maintain a clean, polished look across the bike's hardware. This hardware is part of a comprehensive 400-piece assortment that includes ten different sizes ranging from #6 to 5/8 inch. These washers are sold in refill packs, making them an ideal choice for mechanics who need to replenish their hardware trays with corrosion-resistant components for various custom and repair applications.
