Split lock washers apply spring tension under a fastener head or nut, resisting loosening caused by vibration and thermal cycling. This washer carries a zinc plated finish for basic corrosion resistance in general-duty applications. The inside diameter ranges from 0.314 to 0.322 inches and the outside diameter ranges from 0.489 to 0.586 inches, with a nominal thickness of 0.078 inches. Electricians, plumbers, HVAC technicians, and general mechanical trades use split lock washers as a standard fastener hardware component in panel, bracket, and equipment assembly work.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for residential and light commercial mechanical assemblies where a 5\/16 inch fastener is specified and basic vibration resistance is required. Common applications include securing electrical enclosures, HVAC equipment panels, plumbing brackets, and structural hardware where Grade 2 steel is acceptable for the load and environment. The zinc plated finish provides a degree of protection in dry to mildly humid indoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for general-duty fastener assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc plated finish offers basic corrosion resistance for indoor and dry-environment use\u003c\/li\u003e\n  \u003cli\u003eSplit lock design applies spring tension to resist fastener loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eInside diameter range of 0.314 to 0.322 inches fits standard 5\/16 inch screws and bolts\u003c\/li\u003e\n  \u003cli\u003eOutside diameter range of 0.489 to 0.586 inches suits standard 5\/16 inch fastener clearance holes\u003c\/li\u003e\n  \u003cli\u003eNominal thickness of 0.078 inches for consistent seating under fastener heads and nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard split lock washer for use with 5\/16 inch screws and bolts in inch-measurement fastener assemblies requiring Grade 2 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall split lock washers between the fastener head or nut and the mating surface before torquing. Ensure the washer seats flat with the split ends contacting both surfaces before final tightening. Follow applicable mechanical or electrical codes when assembling equipment panels and enclosures. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective spring tension.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\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\u003eMinimum Outside Diameter\u003c\/strong\u003e: 0.489 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.586 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Thickness\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\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: 81923799\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714298904882,"sku":"81923799","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c7d98bdbdfaaaa954cd9a7ddafc49aa.jpg?v=1788499041","url":"https:\/\/voomisupply.com\/products\/value-collection-81923799-split-lock-washer-5-16-in-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
