Value Collection LWIS062GUSA-100BX Split Lock Washer 100

Product Description

The VALUE COLLECTION LWIS062GUSA-100BX is a steel split lock washer designed for use with 5/8 inch fasteners. It features a hot-dipped galvanized finish that provides corrosion resistance in demanding environments. The washer measures 0.572 to 0.574 inches inside diameter and 0.965 to 0.971 inches outside diameter, with a thickness of 0.141 inches. The split design creates tension under a fastener head or nut, resisting loosening caused by vibration or thermal cycling. This box quantity includes 100 washers. Electricians, plumbers, HVAC technicians, and general contractors use this type of washer in mechanical assemblies, pipe hangers, conduit supports, and structural connections.

Split lock washers in this size range are widely used in both residential and light commercial construction and mechanical service work. They are appropriate wherever a 5/8 inch screw or bolt requires vibration resistance at the fastener seat. Common applications include equipment mounting, duct hangers, pipe supports, and structural steel connections. The hot-dipped galvanized finish makes these suitable for indoor and outdoor installations where moisture exposure is a factor.

Compatibility

Designed for use with 5/8 inch screws and bolts measured in the inch system. Suitable for standard mechanical, structural, and trade-service assemblies requiring a split lock washer at this screw size. Does not meet military specifications.

Installation Notes

Install between the fastener head or nut and the mating surface with the split ends oriented to bite into both surfaces as the fastener is tightened. Power down or de-energize any equipment before working on assemblies that carry electrical current. Follow applicable codes such as NEC for electrical installations or applicable mechanical codes for HVAC and plumbing support connections. Do not reuse a washer that has been fully flattened, as it will no longer provide effective locking action.
