It is designed to resist loosening under vibration and dynamic loads by biting into the bearing surface of the fastener and the mating material when tightened. The washer measures 30.5 mm minimum inside diameter, 48.2 mm outside diameter, and 6 mm thick, with a hardness rating of 44 to 51 HRC. It conforms to DIN 127 fastener standards and is sold as an individual piece with a minimum order quantity of 25 units.\u003c\/p\u003e\n\u003cp\u003eThis washer is used in heavy mechanical assemblies, structural bolted connections, and industrial equipment requiring M30 fastener hardware. It is appropriate for applications where joint integrity under cyclic loading or vibration is a concern. Typical users include millwrights, maintenance mechanics, and industrial contractors working on machinery, steel structures, and heavy equipment. The uncoated finish suits indoor or protected environments where corrosion exposure is minimal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConforms to DIN 127 fastener standard for metric split lock washers\u003c\/li\u003e\n  \u003cli\u003eGrade 8 spring steel construction with 44 to 51 HRC hardness for reliable clamping force\u003c\/li\u003e\n  \u003cli\u003e30.5 mm minimum ID to 31.7 mm maximum ID accommodates M30 fastener shanks\u003c\/li\u003e\n  \u003cli\u003e48.2 mm outside diameter, 6 mm thickness for consistent load distribution\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no plating buildup that could affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications — suitable for commercial and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M30 metric fasteners in assemblies requiring DIN 127 split lock washers.

Always de-energize and lock out equipment before servicing bolted joints on machinery or powered structures. Place the split lock washer between the fastener head or nut and the bearing surface, with the split ends oriented to bite into both surfaces upon final torque. Do not reuse compressed or fully flattened lock washers, as they will not provide adequate spring action.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M30\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: 30.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 31.7 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 48.2 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright, Uncoated\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 744191PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701127840050,"sku":"744191PS","price":3919.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf2c1791e4c8e155d9e56aebd79ad1da.jpg?v=1788398559","url":"https:\/\/voomisupply.com\/products\/value-collection-744191ps-m30-split-lock-washer-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
