Internal tooth lock washers grip the mating surface through serrated inner teeth that bite into both the fastener bearing surface and the workpiece when torque is applied, resisting loosening from vibration and dynamic loads. This washer is sold in a package of 50 pieces. It is suited for general mechanical assembly, electrical panel work, and structural fastening applications where a reliable anti-loosening solution is needed without external tooth interference.\u003c\/p\u003e\u003cp\u003eThis lock washer fits 3\/4 inch screw fasteners and is appropriate for use in residential and light commercial mechanical assemblies, electrical enclosures, and equipment mounting applications. The internal tooth design makes it suitable where a clean outer edge is required and the washer must remain concealed beneath the fastener head. Electricians, HVAC technicians, millwrights, and general maintenance trades commonly use internal tooth lock washers in panel builds and equipment installation work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal tooth design resists loosening under vibration without protruding beyond the fastener head\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides corrosion resistance for indoor and light-duty outdoor use\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets standard commercial fastener requirements\u003c\/li\u003e\n\u003cli\u003eInside diameter range of 0.769 to 0.795 inches accommodates standard 3\/4 inch fasteners\u003c\/li\u003e\n\u003cli\u003eOutside diameter range of 1.22 to 1.245 inches provides adequate bearing surface\u003c\/li\u003e\n\u003cli\u003ePackage of 50 pieces supports job-site and shop inventory needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/4 inch screw fasteners in standard mechanical, electrical, and structural assembly applications where an internal tooth lock washer is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no special tools beyond standard hand or power fastening equipment. Ensure the mating surface is clean and free of debris so the washer teeth can seat properly against both the fastener and the workpiece. Never reuse a lock washer that has been fully compressed, as the teeth will not re-engage effectively. Follow applicable codes such as NEC Article 110 for electrical enclosure hardware or the relevant mechanical code for structural fastener applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooth Type\u003c\/strong\u003e: Internal Tooth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Inside Diameter\u003c\/strong\u003e: 0.769 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 0.795 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Outside Diameter\u003c\/strong\u003e: 1.22 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 1.245 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161801\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: -31359-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694205501746,"sku":"-31359-1","price":40.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b84361fa09bff8f21cd1a00b114abb2a.jpg?v=1788321677","url":"https:\/\/voomisupply.com\/products\/value-collection-31359-1-lock-washer-3-4-in-steel-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
