It features an internal tooth configuration that bites into the bearing surface of the screw head or nut and the mating workpiece, creating mechanical resistance to rotation. Manufactured from Grade 2 spring steel with a zinc-plated finish for basic corrosion resistance, this washer measures 2.2mm inside diameter and 4.5mm outside diameter with a 0.3mm thickness. It is used in light-duty mechanical assemblies where compact fastener retention is required, and is installed by electricians, mechanical assemblers, and maintenance technicians working with M2 fasteners.\u003c\/p\u003e\n\u003cp\u003eThis lock washer is suited for residential and commercial light-duty applications including control panel assemblies, small appliance hardware, electronics enclosures, and precision mechanical sub-assemblies using M2 screw fasteners. Its compact outside diameter makes it appropriate for tight-clearance installations where larger washers would not fit. Each order is fulfilled in a package quantity of one, with a minimum order quantity of 200 pieces per transaction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal tooth design bites into bearing surface to resist loosening under vibration\u003c\/li\u003e\n  \u003cli\u003e2.2mm inside diameter sized for M2 screws\u003c\/li\u003e\n  \u003cli\u003e4.5mm outside diameter and 0.3mm thickness for compact, low-profile fitment\u003c\/li\u003e\n  \u003cli\u003eGrade 2 spring steel construction provides reliable spring-back retention force\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion protection in dry or mildly humid environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M2 screw fasteners in light-duty mechanical and electrical assemblies requiring internal tooth lock washer retention.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall by placing the washer on the fastener shank between the screw head and the workpiece surface before driving the fastener. Ensure the toothed face contacts the workpiece or fastener bearing surface to engage the locking action. Power down any electrical assembly before servicing fasteners on live panels. Do not reuse lock washers that have been fully compressed, as they will not provide adequate retention force after deformation.\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: 2.2mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.3mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 200\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: 742020PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711610519858,"sku":"742020PS","price":962.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ef23d754415dce97a4458ef66fd304f.jpg?v=1788477578","url":"https:\/\/voomisupply.com\/products\/value-collection-742020ps-m2-internal-tooth-lock-washer","provider":"Voomi Supply","version":"1.0","type":"link"}
