It features a 1.192 inch inside diameter and a 1.83 inch outside diameter, with a thickness of 0.067 inches. The zinc-plated finish provides corrosion resistance for general-purpose fastening applications. Manufactured to Grade 2 specifications, this washer uses internal teeth that bite into the mating surface and fastener head to resist loosening under vibration or dynamic loads. It is a standard hardware component installed by electricians, plumbers, HVAC technicians, and general contractors wherever secure, vibration-resistant fastening is required.\u003c\/p\u003e\n\u003cp\u003eThis internal tooth lock washer is suited for residential and light commercial applications where a 1-1\/8 inch fastener is used. Common install scenarios include panel mounting, equipment attachment, and mechanical assemblies where maintaining clamp load under vibration is a priority. The zinc plating makes it appropriate for indoor or mildly corrosive environments.
