Value Collection LWIS-121USA-100BX Split Lock Washer 100

Product Description

The VALUE COLLECTION LWIS-121USA-100BX is a Number 12 screw split lock washer manufactured from Grade 2 spring steel with a yellow zinc dichromate finish. The split lock design provides tension under a fastener head or nut, resisting loosening caused by vibration and torque relaxation. The washer measures 0.22 inches minimum inside diameter, up to 0.227 inches maximum inside diameter, with a maximum outside diameter of 0.377 inches and a thickness of 0.056 inches. This box contains 100 washers, making it suitable for production assembly, maintenance kits, or service-truck stock. Electricians, HVAC technicians, plumbers, and general trade contractors use split lock washers daily in panel, equipment, and structural fastening applications.

This washer is sized for Number 12 screws in inch-measurement fastening systems. It is appropriate for light to medium-duty mechanical assemblies where vibration resistance is required and a military-specification washer is not called out. Common applications include electrical enclosure assembly, HVAC unit cabinet fastening, sheet-metal work, and equipment mounting where a standard inch-series Number 12 fastener is specified. The yellow zinc dichromate finish provides basic corrosion resistance suitable for indoor and mildly protected outdoor environments.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface before final torque is applied. Ensure the washer seats flat against both mating surfaces before driving the fastener. Power down or de-energize any equipment before servicing fastened assemblies in electrical or HVAC applications. Inspect washers for cracking or deformation and replace any that do not seat properly.
