Gardner-Westcott Lock Nut Metric

18 products — part of all Lock Nut Metric

Gardner-Westcott metric lock nuts give Harley-Davidson builders and technicians the correctly specified hardware to prevent fastener loosening in metric-thread applications subject to the vibration and thermal cycling of regular riding. Lock nuts add a secondary resistance mechanism — either a prevailing torque insert or a distorted thread profile — that maintains clamping force even where a standard hex nut would gradually back off under vibration. As modern Harley-Davidson models and aftermarket accessories increasingly use metric hardware, having a reliable source of properly rated metric lock nuts in the right sizes is essential for any professional or enthusiast build. Gardner-Westcott produce their metric range to close tolerances with finishes that match their broader hardware offering. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries Gardner-Westcott metric fasteners as part of a comprehensive metric and USA-thread hardware range.
