Value Collection LWIS1000USA-050BX Split Lock Washer 50 Pack

Product Description

The VALUE COLLECTION LWIS1000USA-050BX is a steel split lock washer designed for use with 1-inch screws. The split design bites into the bearing surface and fastener to resist loosening from vibration and torque relaxation. The zinc plated finish provides corrosion resistance for general indoor and light-duty outdoor fastening applications. Inside diameter runs 1.003 to 1.024 inches, outside diameter runs 1.656 to 1.661 inches, and thickness is 0.25 inches. This washer is installed by maintenance technicians, electricians, plumbers, pipefitters, and general contractors wherever mechanical vibration or thermal cycling could back out a threaded fastener.

This split lock washer suits residential and commercial applications involving 1-inch fasteners in steel, aluminum, and other structural assemblies. Typical installations include pipe hangers, equipment mounting, panel support frames, and mechanical room hardware. The zinc plating makes it a practical choice for areas with moderate moisture exposure. Sold in a minimum quantity of 50 pieces per order to support job-site and shop restocking needs.

Installation Notes

Split lock washers are installed between the fastener head or nut and the bearing surface before torquing down. Ensure the mating surfaces are clean and free of debris to allow full seating of the washer. Always de-energize or depressurize equipment before accessing fastened assemblies per applicable safety codes. Do not reuse a split lock washer that has been fully compressed flat, as the spring tension will not be restored.
