Value Collection R63082224 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION R63082224 is a stainless steel internal tooth lock washer designed for use with 1/2 inch screws. It features an inside diameter of 0.53 inches and an outside diameter of 0.985 inches, with a thickness of 0.045 inches. Manufactured from Grade 410 stainless steel, this washer provides reliable fastener retention by biting into both the mating surface and the fastener bearing face under load. Electricians, plumbers, HVAC technicians, and mechanical contractors use internal tooth lock washers to prevent loosening caused by vibration or thermal cycling in equipment assemblies and panel installations.

This washer is suited for light to medium-duty fastening applications where corrosion resistance is required. Grade 410 stainless steel offers adequate strength and moderate corrosion resistance, making it appropriate for indoor mechanical assemblies, electrical panels, equipment enclosures, and similar trade installations. It is sold in minimum order quantities of 100 pieces per purchase, with individual package quantities of 1, making it practical for stocking and job-lot purchasing in trade environments.

Installation Notes

Installation is performed by placing the washer on the fastener shank against the bearing surface before driving the screw or bolt. Ensure the mating surface is clean and free of debris so the teeth can seat properly. Follow applicable codes such as the NEC for electrical installations when selecting hardware for panel or equipment work. Do not reuse lock washers that have been fully compressed, as the locking function may be diminished.
