Value Collection LWIS0500USA-10LBBX Split Lock Washer

Product Description

The VALUE COLLECTION LWIS0500USA-10LBBX is a Grade 2 spring steel split lock washer sized for 1/2 inch screws. It features a zinc plated finish and is manufactured to inch system dimensions. The inside diameter runs from 0.506 to 0.518 inches, with a maximum outside diameter of 0.873 inches and a thickness of 0.125 inches. Split lock washers like this one are installed under a fastener head or nut to create tension that resists loosening caused by vibration and dynamic loads. This part is appropriate for general mechanical assembly work across HVAC, plumbing, electrical, and structural fastening applications where a standard inch-series locking washer is required.

This split lock washer is suited for residential and commercial assembly applications involving 1/2 inch fasteners. Typical uses include panel mounting, equipment brackets, pipe hangers, electrical enclosures, and mechanical equipment bases. The zinc plated finish offers baseline corrosion resistance for indoor and light-duty outdoor service environments. It does not meet military specifications and is intended for standard commercial and industrial fastening use.

Installation Notes

Split lock washers are installed by a mechanic, technician, or tradesperson as part of a bolted joint assembly. Place the washer between the fastener head or nut and the mating surface before torquing the fastener. Ensure mating surfaces are clean and free of debris to allow proper seating. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the fastener size and joint material.
