Description
This zinc indoor lock washer #4 from HILLMAN is a hardened split lock washer designed to resist loosening and keep threaded connections snug under vibration or movement. Its zinc finish helps resist corrosion in interior environments while providing a reliable bite against nut and bolt surfaces. Use it wherever small fasteners need extra security—cabinet hinges, appliance mounts, light fixtures, shelving brackets and furniture assemblies benefit from the added retention these washers deliver. The compact #4 size works with corresponding screws and bolts to maintain clamping force over time, reducing the need for frequent retightening. For DIYers and pros tackling indoor repair, assembly, and maintenance tasks, this washer offers a simple, durable way to improve the reliability of mechanical connections.
