Value Collection LWIS0501USA-100BX Split Lock Washer 100pk

Product Description

The VALUE COLLECTION LWIS0501USA-100BX is a Grade 2 spring steel split lock washer designed for use with 1/2 inch screws and fasteners. The washer features a zinc yellow dichromate finish that provides corrosion resistance in general-purpose mechanical and structural assemblies. With a minimum inside diameter of 0.502 inches, a maximum outside diameter of 0.869 inches, and a thickness of 0.125 inches, this washer meets standard inch-measurement specifications for 1/2 inch fastener applications. This box contains 100 washers. Installation is performed by maintenance technicians, millwrights, pipefitters, and mechanical contractors working across commercial, industrial, and light manufacturing environments.

These split lock washers are suited for use in general mechanical assemblies, equipment mounting, structural fastening, and maintenance repair operations where standard Grade 2 hardware is acceptable. The helical split design bites into mating surfaces under torque to resist loosening from vibration and thermal cycling. They are appropriate for use in indoor and moderate-exposure environments where yellow zinc dichromate-finished hardware meets the corrosion protection requirement. This product does not meet military specifications.

Installation Notes

Power down or de-energize any equipment before servicing fastened assemblies in electrical or mechanical enclosures. Place the split lock washer onto the fastener shank between the nut or bolt head and the mating surface, ensuring the split ends contact the work surface squarely. Tighten fasteners to the torque specification called out in the equipment service documentation. Follow applicable codes and manufacturer instructions for the assembly being serviced.
