Measuring 7\/8-9 thread size with an 11-inch length under head, this fastener features Unified National Coarse (UNC) threading and is partially threaded along its shank. The bright, uncoated finish leaves the steel in its natural state, making it suitable for applications where additional coating is not required. It conforms to ASME B18.2.1 standards, ensuring dimensional consistency for critical assemblies. Maintenance technicians, millwrights, and mechanical contractors typically install this screw in structural, industrial, and heavy equipment applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in industrial machinery, structural steel assemblies, heavy equipment, and mechanical systems that demand high-strength fasteners. The partial threading is appropriate for clamping through thick materials, allowing the unthreaded shank to bear shear loads. Trade professionals in manufacturing, construction, and general maintenance will find this screw applicable wherever a large-diameter, long-length Grade 8 fastener is specified. Its 1-15\/16-inch hex key drive size accommodates standard industrial wrenching tools.\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\u003ePartially threaded shank supports shear-load bearing in thick-section assemblies\u003c\/li\u003e\n  \u003cli\u003eUNC thread form (7\/8-9) for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating to interfere with precise dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for consistent dimensional standards\u003c\/li\u003e\n  \u003cli\u003e1-15\/16-inch hex drive size for use with standard industrial wrenches or sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance fastener for industrial machinery, structural assemblies, and heavy equipment requiring a 7\/8-9 UNC, Grade 8 hex head cap screw with an 11-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, mechanic, or maintenance technician familiar with high-strength fastener procedures. De-energize and lock out all affected equipment before beginning fastener replacement or assembly work, following applicable OSHA lockout\/tagout procedures. Use a calibrated torque wrench sized for a 1-15\/16-inch hex drive to achieve the specified clamp load per your engineering or equipment manual. Do not substitute a lower-grade fastener in any application that specifies 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: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 11 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\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: 1-15\/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\u003eWeight\u003c\/strong\u003e: 2 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: 451280BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717112267058,"sku":"451280BR","price":40.02,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_d3fa107d-84a2-434c-86ea-af7f27a708c0.jpg?v=1788535863","url":"https:\/\/voomisupply.com\/products\/value-collection-451280br-hex-head-cap-screw-7-8-9-x-11-in","provider":"Voomi Supply","version":"1.0","type":"link"}
