It features an inside diameter of 0.795 inches and an outside diameter of 1.245 inches, with a thickness of 0.055 inches. Constructed from Grade 410 stainless steel, it delivers solid corrosion resistance and reliable holding strength in demanding mechanical and industrial assemblies. The serrated external teeth bite into the mating surface under torque, resisting loosening from vibration and thermal cycling. Plumbers, HVAC technicians, electricians, and millwrights use these washers wherever bolt retention and surface protection are needed in a single component.\u003c\/p\u003e\n\u003cp\u003eThese external tooth lock washers are suited for residential and commercial mechanical assemblies where fastener security is critical. Common applications include equipment mounting, panel fabrication, electrical enclosures, HVAC unit assembly, plumbing fixture installation, and general structural fastening. Grade 410 stainless steel makes these washers appropriate for both indoor and outdoor environments exposed to moisture or mild corrosives. They are sold in a package quantity of 50, making them practical for job-site stock or shop inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal tooth design grips mating surface to resist fastener backout under vibration\u003c\/li\u003e\n  \u003cli\u003eGrade 410 stainless steel construction for corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.795 inches fits standard 3\/4 inch fasteners\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 1.245 inches provides adequate bearing surface coverage\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.055 inches allows use in tight clearance assemblies\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 50 for efficient job-site and shop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/4 inch screws and bolts in general mechanical, electrical, HVAC, and plumbing assemblies requiring an external tooth lock washer with a 0.795 inch inside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by any trade requiring fastener retention in their scope of work. Place the washer on the fastener with the teeth facing the mating surface before driving the screw or bolt. Ensure the mating surface is clean and free of debris so the teeth can seat properly. Do not reuse lock washers that have been fully compressed, as the teeth may no longer provide adequate retention.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel Grade 410\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.795 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.245 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.055 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Screw Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 93813\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712069075250,"sku":"93813","price":36.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97ca6a8546b086ccd19899853b15a814.jpg?v=1788483293","url":"https:\/\/voomisupply.com\/products\/value-collection-93813-external-tooth-lock-washer-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
