Value Collection 93823 Internal Tooth Lock Washer 100-pack

Product Description

The VALUE COLLECTION 93823 is a Grade 410 stainless steel internal tooth lock washer sized for No. 8 screws. It features an inside diameter of 0.176 inches and an outside diameter of 0.34 inches, with a thickness of 0.023 inches. The internal serrated teeth bite into both the fastener bearing surface and the mating material to resist loosening caused by vibration and torque. Each package contains 100 washers. This washer is installed by electricians, plumbers, HVAC technicians, and general trade mechanics wherever a reliable anti-loosening fastener solution is needed in corrosion-prone environments.

The 93823 internal tooth lock washer is suited for light-duty fastening applications where stainless steel is required for corrosion resistance. Typical installations include electrical enclosures, HVAC sheet metal assemblies, plumbing fixture mounting, and other indoor or outdoor mechanical assemblies using No. 8 machine screws or bolts. The Grade 410 stainless construction provides adequate corrosion resistance for a wide range of service environments without the cost of higher-alloy stainless grades.

Installation Notes

Install this washer between the fastener head and the mating surface before driving the screw to rated torque. Ensure mating surfaces are clean and free of debris so the serrated teeth can seat properly. Stainless fastener components should be handled with care to avoid cross-contamination with carbon steel tools that may promote surface rust. No special tools are required beyond standard hand or power drivers appropriate for the fastener type.
