Value Collection LWIS100USA-050BX Split Lock Washer 50 Pack

Product Description

The VALUE COLLECTION LWIS100USA-050BX is a steel split lock washer sized for 1-inch screws. It features a bright, uncoated finish and is designed to resist fastener loosening under vibration and dynamic loads. The inside diameter ranges from 1.003 to 1.024 inches, the outside diameter ranges from 1.656 to 1.661 inches, and the washer is 0.25 inches thick. This pack contains 50 individual washers sold as a single package quantity. Maintenance technicians, millwrights, plumbers, electricians, and HVAC installers commonly use split lock washers when assembling mechanical connections that must stay tight through repeated thermal cycling or vibration.

Split lock washers in this size class are suited to a wide range of commercial and industrial assembly tasks wherever 1-inch fasteners are used. Typical applications include equipment mounting, pipe support bracketing, electrical panel assembly, and structural hardware connections in both new construction and retrofit work. The uncoated bright steel finish is appropriate for dry or protected indoor environments where corrosion resistance is not a primary requirement.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before the fastener is torqued down. Ensure the split ends seat fully against both surfaces as the fastener is tightened. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective locking tension. Follow applicable code requirements, including NEC or IPC guidelines, when using fasteners in electrical or plumbing assemblies.
