Manufactured from Grade 8 steel with an uncoated finish, this fastener meets ASME B18.2.1 dimensional standards. The 5\/16-18 UNC thread size and 4-1\/2 inch length under head make it well suited for through-bolt and clamped joint configurations where a longer grip length is required. Machinists, millwrights, maintenance technicians, and general contractors regularly use Grade 8 hex cap screws where tensile strength demands exceed what lower-grade hardware can provide.\u003c\/p\u003e\u003cp\u003eThis fastener is appropriate for use in equipment frames, machinery mounts, structural brackets, and similar load-bearing connections in both residential and commercial settings. The partial thread configuration provides a smooth shank section that is beneficial in shear-loaded joints or applications where the bolt passes through clearance holes before engaging a threaded nut or tapped hole. Sold in packages of 25 units per the supplier pack quantity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for demanding fastening applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded design leaves a smooth shank for shear-loaded joints and clearance-hole installations\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread form for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n\u003cli\u003e4-1\/2 inch length under head accommodates thick material stacks and longer grip lengths\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for dry indoor environments or when a customer-applied coating is planned\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 for dimensional accuracy and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with 5\/16-18 UNC nuts, washers, and tapped holes conforming to ASME thread standards in general mechanical and structural assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with fastener torque requirements for Grade 8 hardware. Always use a calibrated torque wrench and refer to the applicable engineering specification or fastener torque chart for the correct clamp load. Ensure mating threads are clean and free of debris before installation. Do not mix Grade 8 fasteners with lower-grade nuts, as mismatched hardware can compromise joint integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4-1\/2 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 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage 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\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: C703084\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702653681970,"sku":"C703084","price":33.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dec39d09d6451d4c7fd42fb45000e979.jpg?v=1788412558","url":"https:\/\/voomisupply.com\/products\/value-collection-c703084-hex-head-cap-screw-5-16-18-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
