The helical split design creates a spring tension that resists loosening caused by vibration, torque, and thermal cycling. The yellow zinc dichromate finish provides corrosion resistance in moderate-duty environments. With an inside diameter of 0.314 inches, a maximum outside diameter of 0.583 inches, and a thickness of 0.078 inches, this washer meets standard dimensional requirements for 5\/16 inch fastener assemblies. This box contains 100 washers. Licensed tradespeople, maintenance mechanics, and general contractors rely on split lock washers as a cost-effective method to maintain clamp load on bolted joints over time.\u003c\/p\u003e\u003cp\u003eThese split lock washers are suited for general industrial, commercial, and residential mechanical assemblies where vibration resistance is required. Common applications include structural steel connections, equipment mounting, electrical panel work, HVAC equipment fastening, and plumbing fixture installation. The inch-system dimensioning makes these washers compatible with standard fractional fastener hardware commonly used across North American trade and construction work. The yellow zinc dichromate finish is appropriate for indoor and lightly controlled outdoor environments where moderate corrosion protection is adequate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 2 spring steel construction delivers consistent clamping force and bite under load\u003c\/li\u003e\n\u003cli\u003eSplit helical design resists loosening from vibration and dynamic loading\u003c\/li\u003e\n\u003cli\u003eYellow zinc dichromate finish provides moderate corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInside diameter range of 0.314 to 0.322 inches fits standard 5\/16 inch fasteners\u003c\/li\u003e\n\u003cli\u003ePack of 100 supports volume fastener work and reduces per-unit cost\u003c\/li\u003e\n\u003cli\u003eInch measurement system aligns with North American fractional fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5\/16 inch screws and bolts in standard inch-system fastener assemblies.

Ensure mating surfaces are clean and free of debris before assembly. Always de-energize or shut down equipment before performing any fastener work on electrical, HVAC, or mechanical systems. These washers do not meet military specifications and should not be substituted in applications requiring MIL-spec hardware.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Grade 2 Spring Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Yellow Zinc Dichromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Inside Diameter\u003c\/strong\u003e: 0.314 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 0.322 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.583 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161801\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: LWIS0311USA-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712541524274,"sku":"LWIS0311USA-100BX","price":662.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09225f434ba4380ae42da34e58a4d8b9.jpg?v=1788486568","url":"https:\/\/voomisupply.com\/products\/value-collection-lwis0311usa-100bx-split-lock-washer-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
