The internal tooth configuration bites into both the mating surface and the fastener head, creating mechanical resistance against rotation. Made from Grade 2 spring steel with a zinc-plated finish, this washer delivers corrosion resistance and reliable spring action in light-duty mechanical and electrical assemblies. It measures 2.8mm inside diameter and 5.5mm outside diameter, with a thickness of 0.4mm. Electricians, HVAC technicians, and mechanical assemblers use this washer in panel work, equipment mounting, and control board fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for use with M2.5 screws in residential and commercial applications where vibration resistance is needed at small fastener sizes. Typical uses include securing terminal blocks, control boards, junction box covers, and light-duty mechanical subassemblies. The zinc plating provides moderate corrosion protection appropriate for indoor and sheltered environments. Sold individually per unit, with a minimum order quantity of 200 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal tooth design bites into fastener and mating surface to resist loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eSpring steel construction provides consistent clamping force and spring-back\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in indoor and sheltered applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 material grade for light-duty mechanical and electrical fastening\u003c\/li\u003e\n  \u003cli\u003e2.8mm inside diameter fits M2.5 screws; 5.5mm outside diameter; 0.4mm thickness\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M2.5 screws as an internal tooth lock washer in light-duty mechanical and electrical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this lock washer between the fastener head and the mating surface, with the teeth facing the fastener head for maximum grip. Ensure the mating surface is clean and free of debris before assembly. Do not reuse lock washers that have been fully compressed, as spring action may be reduced. This component is typically installed by electricians or mechanical technicians following applicable assembly standards.\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: 2.8mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.4mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161801\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 742061PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694647935282,"sku":"742061PS","price":1261.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4fedf3b4627858785e3dbf43f5df921.jpg?v=1788326747","url":"https:\/\/voomisupply.com\/products\/value-collection-742061ps-m2-5-internal-tooth-lock-washer","provider":"Voomi Supply","version":"1.0","type":"link"}
