Value Collection LWIS250GUSA-005BX Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION LWIS250GUSA-005BX is a Grade 8 spring steel split lock washer designed for use with 2-1/2 inch screws and bolts. It features a hot-dipped galvanized finish that provides corrosion resistance in demanding environments. The washer measures 2.532 to 2.557 inches inside diameter with a maximum outside diameter of 3.485 inches and a thickness of 0.44 inches. Split lock washers work by biting into both the fastener and mating surface under load, resisting loosening caused by vibration or torque relaxation. This part is used by maintenance technicians, millwrights, and contractors in structural and mechanical assemblies.

This split lock washer is suited for heavy-duty bolted connections in industrial, commercial, and construction applications where fastener retention under vibration or dynamic loading is required. The Grade 8 material rating and hot-dipped galvanized finish make it appropriate for outdoor, high-stress, or corrosive-environment installations. It is sized for 2-1/2 inch fasteners and is sold with a minimum order quantity of 5 pieces per order, with a package quantity of 1 per pack.

Installation Notes

Split lock washers are installed by placing the washer on the fastener shank between the bolt head or nut and the mating surface before torquing. Follow applicable torque specifications for the Grade 8 fastener being used. Ensure the mating surface is clean and flat so the washer seats properly. Power down or de-energize any equipment before performing fastener work on mechanical or electrical assemblies.
