Manufactured to ASME B18.2.1 standards, this fastener is designed for high-strength bolted connections in heavy-duty mechanical, structural, and industrial applications. Grade 8 material provides significantly higher tensile strength than Grades 2 or 5, making it a standard choice when joint integrity under load is critical. The hex drive accepts a 1-11\/16 inch wrench. Installation is performed by mechanics, millwrights, and field technicians working on equipment assemblies, mounting structures, and machinery frames.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in industrial machinery assembly, structural steel connections, heavy equipment mounting, and similar applications requiring a large-diameter, high-strength UNC fastener. The partial thread configuration is typical for clamping applications where the unthreaded shank provides shear resistance across the joint interface. It is sold individually and is appropriate for both OEM assembly and field service replacement work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength in demanding bolted joints\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides shear resistance across clamped interfaces\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread form for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish  -  suitable for dry or lightly oiled indoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003e1-11\/16 inch hex key (wrench) size for use with standard open-end, box, or impact tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1-1\/4-7 UNC hex nuts, washers, and tapped holes conforming to ASME and ANSI inch-series threading standards in Grade 8 or equivalent high-strength fastener applications.\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. Always consult the applicable engineering specification or equipment service manual for required torque values before tightening. Inspect mating threads and bearing surfaces for damage or contamination before assembly. Apply a thread lubricant or anti-seize only when specified by the joint design, as lubrication affects torque-tension relationships for Grade 8 fasteners.\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\/4-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\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\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Wrench Size\u003c\/strong\u003e: 1-11\/16 inches\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: 0.05 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: 451034BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":67650984476978,"sku":"451034BR","price":42.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_ca56e696-b3c0-4dbf-b26b-b6c786b92c99.jpg?v=1790462150","url":"https:\/\/voomisupply.com\/products\/value-collection-451034br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
