Stamped from Grade 410 stainless steel, each washer features internal serrated teeth that bite into the mating surface and fastener bearing face as the joint is torqued, maintaining clamping force over time. The 0.123 inch inside diameter suits number 4 machine screws. Overall outside diameter measures 0.27 inches and thickness is 0.019 inches. These washers are well suited for electrical enclosures, HVAC equipment panels, plumbing fixtures, and any assembly requiring corrosion-resistant fastener retention.\u003c\/p\u003e\u003cp\u003eThese internal tooth lock washers are used in light fastening applications across residential and commercial trade work. Typical installations include terminal connections in electrical panels, equipment chassis, control board mounting, and sheet-metal assemblies where a standard flat washer alone is insufficient. Each pack contains 100 washers, making it practical for service vehicles and shop stock.
