The fastener measures 2.25 inches under the head and features partial threading along the shank. It conforms to ASME B18.2.1 and SAE J429 dimensional and strength standards, making it a dependable choice for structural and mechanical assemblies. The UNC thread form seats reliably in standard tapped holes and mating nuts. Installers in HVAC, plumbing, electrical, and general mechanical trades reach for this size when securing brackets, panels, and equipment frames where a controlled grip length and clamping force are required.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for general-purpose bolted connections in both residential and light commercial applications. Typical uses include securing equipment mounting brackets, junction box enclosures, conduit supports, fan assemblies, and similar structural components. The zinc plating provides a baseline level of corrosion resistance for indoor and sheltered outdoor environments. It is sold individually, with a minimum order quantity of 25 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n  \u003cli\u003e2.25-inch length under head with partial threading for controlled grip length\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for baseline corrosion resistance in sheltered environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC hex head cap screw for use in any application calling for a 5\/16-18 x 2-1\/4-inch Grade 5 fastener in ferrous or non-ferrous assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex wrench, socket, or combination wrench sized for a 5\/16-inch hex head cap screw. Ensure mating threads are clean and free of debris before driving. Always de-energize and lock out equipment before fastening components on electrical or mechanical systems per applicable OSHA and NEC lockout\/tagout procedures. Do not overtighten — follow the torque specifications provided in the equipment manufacturer's service documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\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\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: D30034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695431188786,"sku":"D30034","price":23.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e4ef6b93799c0c2dd4b104283832435.jpg?v=1788334953","url":"https:\/\/voomisupply.com\/products\/value-collection-d30034-hex-head-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
