06559 5/8-18 hex nut zinc

This 5/8-18 fine thread hex nut is manufactured by Gardner-Westcott, a specialist in American-made fasteners for V-Twin motorcycles. Constructed from steel with a zinc-plated finish, it provides essential corrosion resistance for exposed chassis or engine components. The zinc coating offers a clean, traditional look that matches original hardware found on many Harley-Davidson models. This nut is ideal for securing heavy-duty mounting points or axles where a fine pitch is required for precise tensioning and resistance to loosening. These fasteners are sold in packs of 5, ensuring you have replacements ready for your next service or custom build project.
