Value Collection LWIS0431USA-100BX Split Lock Washer 100pk

Product Description

The VALUE COLLECTION LWIS0431USA-100BX is a Grade 2 spring steel split lock washer sized for 7/16-inch screws. The split ring design bites into the fastener and mating surface under torque, resisting loosening from vibration and dynamic loads. Finished in yellow zinc dichromate for corrosion resistance, this washer measures 0.44 inches minimum inside diameter, 0.45 inches maximum inside diameter, and 0.776 inches maximum outside diameter, with a thickness of 0.109 inches. Sold in a box of 100, it suits assembly and maintenance work across mechanical, HVAC, plumbing, and electrical applications.

This split lock washer is used wherever a standard 7/16-inch fastener requires anti-loosening protection in light to medium-duty assemblies. Typical applications include equipment mounting, panel fastening, pipe support hardware, and structural brackets in residential and light commercial work. The yellow zinc dichromate finish provides a baseline level of corrosion resistance suitable for indoor and protected outdoor environments. The inch measurement system and Grade 2 material rating align with common North American hardware specifications.

Installation Notes

Split lock washers are installed by a licensed technician or qualified mechanic between the fastener head or nut and the mating surface before final torquing. Ensure the fastener, washer, and mating surface are clean and free of debris before assembly. Do not reuse a washer that has been fully compressed flat, as the locking action will be lost. Follow applicable mechanical or structural codes for the specific assembly type.
