Manufactured from Grade 8 steel with a bright, uncoated finish, this fastener delivers the tensile strength required in demanding load-bearing connections. The partially threaded shank measures 15 inches under the head on a 1-3\/8-12 UNF thread specification, conforming to ASME B18.2.1. At 6.98 pounds, it is suited for heavy bolted joints where lesser fasteners would be inadequate. A 2-1\/16-inch hex key size accommodates standard industrial wrenching tooling.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in applications where Grade 8 strength and fine-thread UNF engagement are required, including heavy equipment assemblies, industrial machinery mounting, and structural bolted connections. The partially threaded shank allows for shear loading across the unthreaded section, making it appropriate for joints where grip length and bearing load matter. Fabricators, millwrights, and maintenance mechanics working on heavy-duty equipment will find this fastener well suited to high-torque, high-clamp-force installations.\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 ratings\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-12 UNF fine thread for precise clamp control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e15-inch length under head accommodates thick or stacked structural members\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear loading across the grip length\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating thickness to account for in torque calculations\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.2.1 inch-series hex head cap screw for use in any application requiring a 1-3\/8-12 UNF Grade 8 fastener with a 15-inch grip length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright familiar with high-strength fastener torque requirements for Grade 8 hardware. Verify that mating tapped holes or nuts match the 1-3\/8-12 UNF thread specification before installation. The uncoated finish means no de-rating of torque values for coating thickness, but lubrication practices should follow the applicable engineering specification or torque table for dry versus lubricated conditions. Inspect threads for damage and confirm proper engagement depth before applying final torque.\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\/8-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 \/ Coating\u003c\/strong\u003e: Bright \/ Uncoated\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: 6.98 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: 451760BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709430464818,"sku":"451760BR","price":49.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c766077d973988d11dd6f0dca63248d.jpg?v=1788456324","url":"https:\/\/voomisupply.com\/products\/value-collection-451760br-hex-cap-screw-1-3-8-12-x-15-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
