With a 1-3\/8-6 UNC thread size and a 5-1\/2-inch length under head, this partially threaded fastener meets ASME B18.2.1 dimensional standards. The bright, uncoated finish indicates bare steel without additional plating or coating treatment. Grade 8 classification means the screw meets elevated proof load, tensile strength, and hardness requirements, making it appropriate for structural, heavy equipment, and high-load assembly work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial machinery, structural steel assemblies, heavy equipment fabrication, and maintenance applications where a large-diameter, high-strength fastener is required. The partially threaded shank is suited to bolted joints where a smooth shank section through the grip area is preferred for shear resistance or precise fit. Typically installed by millwrights, industrial mechanics, or field maintenance technicians working on equipment requiring heavy-duty fastening.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets elevated tensile and proof load requirements\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-6 UNC thread size for large-diameter, high-load applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a smooth grip section for shear-loaded joints\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no plating or coating applied\u003c\/li\u003e\n  \u003cli\u003e2-1\/16-inch hex key size for standard wrench drive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.2.1 hex head cap screw for use in applications requiring a 1-3\/8-6 UNC Grade 8 partially threaded fastener with a 5-1\/2-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 2-1\/16-inch open-end, box, or socket wrench. Always verify that the mating nut and tapped hole thread specification matches 1-3\/8-6 UNC before assembly. De-energize, depressurize, or otherwise isolate the equipment being serviced prior to fastener replacement. Follow applicable industry torque guidelines for Grade 8 fasteners at this diameter, sourced from the equipment manufacturer or a current fastener engineering reference.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-6 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5-1\/2 inches\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 2-1\/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: 3 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: 451654BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714398191922,"sku":"451654BR","price":28.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_fe6428f7-76d8-401c-ac24-f4ce7b2bd615.jpg?v=1788500932","url":"https:\/\/voomisupply.com\/products\/value-collection-451654br-hex-head-cap-screw-grade-8-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
