It is manufactured from Grade 2 spring steel with a zinc-plated finish that provides basic corrosion resistance in general-purpose fastening assemblies. The washer measures 13.0mm inside diameter and 20.5mm outside diameter with a 1.0mm thickness. Internal teeth bite into the bearing surface and fastener head as the nut or bolt is torqued, creating a mechanical lock that resists loosening from vibration. This type of washer is a standard hardware component installed by electricians, plumbers, HVAC technicians, millwrights, and general maintenance professionals wherever an M12 fastener requires additional anti-loosening retention.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for residential and commercial mechanical assemblies, electrical panel work, equipment mounting, and general structural fastening where an M12 bolt or screw is specified. The internal tooth design keeps the washer centered on the fastener shank during installation, which simplifies assembly in tight clearance situations. The zinc-plated spring steel construction is appropriate for indoor and light-duty applications. This item is sold individually but carries a minimum order quantity of 100 pieces, making it practical for shop stock, service vans, or production-line use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal tooth design centers on M12 fastener shank and bites into mating surface under load to resist vibration loosening\u003c\/li\u003e\n  \u003cli\u003eSpring steel construction provides consistent tooth tension and elastic recovery during torque-down\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish delivers basic corrosion protection for indoor and low-moisture environments\u003c\/li\u003e\n  \u003cli\u003eGrade 2 material classification suitable for standard general-purpose fastening applications\u003c\/li\u003e\n  \u003cli\u003e1.0mm thickness fits standard M12 bolt clearance stacks without excessive added height\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 pieces supports bulk restocking for service and production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard internal tooth lock washer for use with M12 screws and bolts in general-purpose mechanical, electrical, and structural fastening assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the teeth facing the fastener head or nut bearing surface, not the workpiece, unless application requirements specify otherwise. Ensure the mating surfaces are clean and free of debris so the teeth can seat properly under torque. Do not reuse lock washers that have been fully compressed or show signs of tooth deformation, as spring recovery will be reduced. Follow applicable mechanical or electrical code requirements for fastener torque specifications relevant to the specific assembly being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Type\u003c\/strong\u003e: Internal 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\u003eCompatible Screw 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\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: 742116PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718128435506,"sku":"742116PS","price":2647.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d9f4be51dea06b9b76d39a30b4514c9.jpg?v=1788550082","url":"https:\/\/voomisupply.com\/products\/value-collection-742116ps-m12-internal-tooth-lock-washer","provider":"Voomi Supply","version":"1.0","type":"link"}
