Value Collection LWIS050GUSA-100BX Split Lock Washer 100

Product Description

The VALUE COLLECTION LWIS050GUSA-100BX is a 1/2 inch screw-size split lock washer made from steel with a hot-dipped galvanized finish. Split lock washers apply spring tension under a fastener head or nut, resisting loosening caused by vibration or thermal cycling. This washer features an inside diameter of 0.509 to 0.512 inches and an outside diameter of 0.869 to 0.873 inches, with a thickness of 0.125 inches. It is sold in a minimum order quantity of 100 pieces. Mechanical contractors, electricians, plumbers, and general tradespeople use these washers in structural and equipment-mounting applications where fastener retention is critical.

This split lock washer is suited for use with 1/2 inch fasteners in residential and commercial trade applications. Typical install scenarios include mounting HVAC equipment, electrical enclosures, pipe hangers, and structural brackets where vibration or movement could back off a standard hex nut or bolt. The hot-dipped galvanized finish provides corrosion resistance in damp or outdoor-exposed environments. These washers are compatible with standard 1/2 inch bolts and machine screws following inch measurement conventions.

Installation Notes

Split lock washers are installed by mechanical, electrical, or plumbing tradespeople using standard hand or power tools. Place the washer between the fastener head or nut and the mating surface before tightening. Do not reuse a split lock washer that has been fully flattened, as it will no longer provide effective spring tension. Follow applicable torque guidelines for the fastener grade and application per relevant mechanical or electrical codes.
