Measuring 5\/8-11 thread size with a 16-inch length under head, this fastener uses a Unified National Coarse (UNC) thread form and is partially threaded along its shank. The bright, uncoated finish leaves the steel bare, making it suitable for applications where a coating-free surface is required or where the installer will apply a separate treatment. It conforms to ASME B18.2.1, the standard governing inch-series hex cap screws. Installation requires a 15\/16-inch hex key or socket. Installers in mechanical, structural, and industrial trades rely on this fastener for demanding connections requiring high clamp load.\u003c\/p\u003e\n\u003cp\u003eThis fastener is appropriate for heavy-duty bolted connections in industrial machinery, structural steel assemblies, agricultural equipment, and general mechanical fabrication. The Grade 8 rating makes it suited for high-stress joints where standard Grade 5 or lower hardware would be insufficient. The partial thread configuration provides a smooth shank section useful in joints requiring a bearing surface or precise shear load transfer. Sold individually per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread size with 16-inch length under head\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for shear-bearing and clamping applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no plating or treatment applied\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 inch-series hex cap screw standard\u003c\/li\u003e\n  \u003cli\u003e15\/16-inch hex drive size for standard socket or open-end wrench installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for any application requiring a 5\/8-11 UNC hex head cap screw at 16 inches length under head, Grade 8 steel, conforming to ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or structural tradesperson familiar with high-strength fastener procedures. Always verify the mating nut or tapped hole is rated to Grade 8 or equivalent before assembly. Use a calibrated torque wrench and follow the torque specification provided by the equipment manufacturer or applicable structural code for 5\/8-11 Grade 8 fasteners. Inspect threads for damage before installation and never reuse a fastener that shows signs of thread deformation or hydrogen embrittlement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 16 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: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 15\/16 inches\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\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 451186BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689402040626,"sku":"451186BR","price":37.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_5c87284d-fb69-4dee-8bba-6c991c8ba165.jpg?v=1788258895","url":"https:\/\/voomisupply.com\/products\/value-collection-451186br-hex-head-cap-screw-5-8-11-x-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
