Value Collection MP93781 Split Lock Washer 1/2 in 18-8 Ss

Product Description

The VALUE COLLECTION MP93781 is a split lock washer designed for use with 1/2 inch screws and fasteners. Manufactured from 18-8 stainless steel, it provides reliable resistance to corrosion in demanding service environments. The washer measures 0.502 to 0.512 inches inside diameter, with a maximum outside diameter of 0.869 inches and a thickness of 0.125 inches. The split design creates spring tension under a fastener head or nut, resisting loosening from vibration and torque cycling. Licensed trades including electricians, HVAC technicians, plumbers, and pipefitters use split lock washers as a standard component in mechanical assembly and equipment mounting applications.

This split lock washer is suited for general mechanical fastening tasks across residential and commercial applications. Its stainless steel construction makes it appropriate for outdoor, wet, or corrosive environments where carbon steel fasteners would be prone to rust. Typical uses include equipment mounting, pipe support brackets, electrical enclosures, and structural fastening assemblies where vibration resistance is required. The inch-measurement system sizing is consistent with standard SAE fastener specifications.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface prior to tightening. Ensure the fastener and mating threads are clean and free of debris before assembly. Power down or de-energize any equipment before servicing fastened assemblies in electrical or mechanical systems. Follow applicable codes such as the NEC or IFGC when installing fasteners in code-regulated systems.
