Manufactured from Grade 8 spring steel with a zinc plated finish, this washer delivers a Rockwell hardness of 44 to 51 HRC, providing the elastic resistance needed to resist fastener loosening caused by vibration and thermal cycling. With an inside diameter of 7.1 to 7.5mm, a maximum outside diameter of 12.8mm, and a thickness of 1.7mm, the 42453 conforms to DIN 127 standards. Electricians, millwrights, and mechanical contractors use this type of hardware in panel assemblies, equipment mounting, and structural fastening applications.\u003c\/p\u003e\u003cp\u003eThis split lock washer is suited for metric fastening applications across industrial, commercial, and light structural environments. It pairs with M7 screws and bolts where axial load and vibration resistance are required. The zinc plated finish provides baseline corrosion protection in moderate exposure conditions. This washer is sold individually per package, with a minimum order quantity of 200 pieces, making it appropriate for MRO stocking, kitting operations, and production line use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 spring steel construction with 44 to 51 HRC hardness range\u003c\/li\u003e\n\u003cli\u003eDIN 127 fastener standard compliance for metric applications\u003c\/li\u003e\n\u003cli\u003eZinc plated finish for moderate corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInside diameter range of 7.1 to 7.5mm accommodates M7 fasteners\u003c\/li\u003e\n\u003cli\u003e1.7mm thickness provides consistent spring action under torque\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 200 units supports production and MRO procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M7 metric screws and bolts in applications conforming to DIN 127 split lock washer specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall this washer between the fastener head or nut and the mating surface before torquing. Power down or de-energize any equipment before servicing fastened assemblies in electrical or mechanical systems. Do not reuse split lock washers that have been fully compressed, as the spring action is reduced after full deflection. Follow applicable mechanical or structural codes for fastener torque requirements based on the assembly being serviced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M7\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: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 44 to 51 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Inside Diameter\u003c\/strong\u003e: 7.1mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 7.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 12.8mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Thickness\u003c\/strong\u003e: 1.7mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 127\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 42453\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692746637618,"sku":"42453","price":30.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fc11b08252ed1fcb784c8d382cef4d0.jpg?v=1788302175","url":"https:\/\/voomisupply.com\/products\/value-collection-42453-m7-split-lock-washer-grade-8-din-127","provider":"Voomi Supply","version":"1.0","type":"link"}
