Manufactured from Grade 8 steel in an uncoated finish, this fastener delivers the tensile strength required for demanding industrial and construction applications. The screw features a 1-1\/2-6 UNC thread and measures 8 inches in length under the head, with partial threading along the shank. It conforms to ASME B18.2.1 dimensional standards, ensuring reliable fitment with standard hardware and tooling used by trade professionals across multiple industries.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy mechanical assemblies, structural steel connections, equipment mounting, and industrial fabrication work where high-strength Grade 8 fasteners are specified. Partial threading is appropriate for applications requiring a smooth shank grip zone to carry shear loads or provide precise clamping without thread engagement across the full bolt length. Machinists, millwrights, ironworkers, pipefitters, and general mechanical contractors routinely specify this fastener class in both residential and commercial construction and maintenance projects.\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 strength\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-6 UNC thread form for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head accommodates thick structural members and stacked assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a smooth grip zone for shear-load and precise clamping applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional precision without coating buildup on thread flanks\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and general-use replacement hex head cap screw for structural and mechanical fastening applications requiring a 1-1\/2-6 UNC thread, Grade 8 steel, and an 8-inch length under head per ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tradespeople using calibrated torque equipment appropriate for Grade 8 fasteners of this diameter. Always consult the relevant structural or equipment specification for the required torque value, as this varies by application and joint design. Inspect mating threads and bearing surfaces for damage or contamination before assembly. Never substitute a lower-grade fastener in an application specifying Grade 8.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 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: 1\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: C50000159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715248619826,"sku":"C50000159","price":77.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c28eb2d4d9e32575ba55f00249d822d4_4d05a118-5922-4fb2-ba77-ff74619df9c8.jpg?v=1788511124","url":"https:\/\/voomisupply.com\/products\/value-collection-c50000159-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
