Designed to seat under bolt or screw heads, the external teeth bite into the mating surface and fastener bearing face as the fastener is torqued, creating mechanical resistance to loosening caused by vibration or dynamic loading. The washer measures 13.0mm inside diameter, 20.5mm outside diameter, and 1.0mm thickness, making it sized for M12 fastener assemblies. The zinc plating provides a base level of corrosion resistance for general-duty applications.\u003c\/p\u003e\n\u003cp\u003eThis lock washer is used in mechanical, electrical, and structural assemblies wherever M12 fasteners require anti-loosening retention. Common installation scenarios include panel mounting, equipment frames, electrical enclosure assembly, and light structural connections in both residential and commercial settings. Electricians, millwrights, assemblers, and general maintenance technicians routinely use external tooth lock washers of this type. The part is sold individually but carries a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal tooth design bites into fastener and mating surface to resist vibration-induced loosening\u003c\/li\u003e\n  \u003cli\u003eGrade 2 spring steel construction provides consistent clamping force across the tooth profile\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion protection for indoor and light-duty outdoor use\u003c\/li\u003e\n  \u003cli\u003e13.0mm inside diameter sized for M12 screws and bolts\u003c\/li\u003e\n  \u003cli\u003e1.0mm thickness suits standard M12 fastener stack-up tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard external tooth lock washer for use with M12 screws and bolts in general mechanical, electrical, and structural fastener assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall the lock washer between the fastener bearing face and the mating surface, with the teeth facing the fastener head or nut. Ensure both mating surfaces are clean and free of coatings that could prevent tooth engagement. Torque the fastener to the value specified for the fastener grade and application per applicable standards. Do not reuse lock washers that have been fully compressed or deformed, as the spring action will not be restored.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Type\u003c\/strong\u003e: External Tooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 13.0mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 20.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1.0mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M12\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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 741116PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703629250866,"sku":"741116PS","price":2535.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34f85bd36e8fb8a7405e29bfbfcca574.jpg?v=1788417698","url":"https:\/\/voomisupply.com\/products\/value-collection-741116ps-m12-external-tooth-lock-washer","provider":"Voomi Supply","version":"1.0","type":"link"}
