It features a 1-1\/8-7 UNC thread size with a 6-1\/2-inch length under head and is partially threaded to allow for a bearing surface on the shank. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets ASME B18.2.1 dimensional standards. It is suitable for structural assemblies, heavy equipment mounting, and industrial maintenance work where high tensile and proof load requirements must be met. Installation requires a 1-11\/16-inch hex wrench or socket.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in a wide range of heavy industrial, mechanical, and structural applications. Its Grade 8 rating makes it appropriate for joints subject to high static and dynamic loads. Typical install scenarios include machinery frames, steel fabrication, equipment bases, and any assembly requiring a high-strength UNC fastener. Trades working in HVAC mechanical rooms, plumbing equipment mounting, and electrical gear installations commonly use Grade 8 hex cap screws for anchoring heavy components to structural steel or concrete-embedded threaded rod.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile strength for demanding load-bearing applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank offers a bearing surface and reduces shear stress at the joint interface\u003c\/li\u003e\n  \u003cli\u003eUNC 1-1\/8-7 thread form for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for dry indoor environments or where coatings would interfere with close-tolerance fits\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for consistent dimensional accuracy across the fastener\u003c\/li\u003e\n  \u003cli\u003eRequires a 1-11\/16-inch hex drive, compatible with standard impact sockets and torque wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard inch-series Grade 8 hex nuts and heavy hex nuts conforming to UNC thread standards in 1-1\/8-7 thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, ironworkers, or maintenance mechanics using a calibrated torque wrench and the appropriate 1-11\/16-inch socket. Always verify that the mating nut or tapped hole is rated for Grade 8 loads before assembly. Inspect threads for damage before installation and never use an impact driver alone to achieve final torque on structural joints. Follow applicable AISC or equipment manufacturer torque specifications for the joint classification.\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\/8-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6-1\/2 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 \/ Coating\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\u003eHex Key Size\u003c\/strong\u003e: 1-11\/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: 2.18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 451009BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707256308018,"sku":"451009BR","price":33.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_74d7d061-1f7f-407e-a169-29b58f0c0e0a.jpg?v=1788439229","url":"https:\/\/voomisupply.com\/products\/value-collection-451009br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
