Sized at 7\/8-9 UNC with a 10-inch length under head, this fastener is partially threaded and driven by a 3\/4-inch hex key. The alloy steel construction and black oxide finish provide strength and corrosion resistance suitable for demanding service conditions. At 9.93 pounds, this is a substantial fastener intended for heavy-duty mechanical work. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming compliance with recognized fastener specifications for strength and dimensional accuracy.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in applications requiring a recessed drive fastener with a high-strength shoulder and clamping force. Typical installations include machinery frames, structural bolted connections, tooling fixtures, and equipment assemblies where a flush or countersunk head profile is needed alongside significant load-bearing capacity. The partially threaded shank provides a smooth bearing surface that resists shear forces at the joint interface, making it a practical choice for precision-fit applications across manufacturing and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread size for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e10-inch length under head provides generous grip range for thick stack assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear resistance at the joint interface\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex drive for use with standard hex keys or Allen-style socket tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength cap screw requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and reduces surface reflectivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 compliant hex socket cap screw for use in any application requiring a 7\/8-9 UNC partially threaded fastener with a 10-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician using a properly sized 3\/4-inch hex key or socket driver. Ensure the mating tapped hole is clean, free of debris, and cut to the correct 7\/8-9 UNC thread specification before installation. Apply thread lubricant or anti-seize compound as required by the application to achieve accurate clamp load. Always de-energize and lock out equipment before removing or replacing structural fasteners.\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: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/4 inches\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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.93 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: 581763BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717803475250,"sku":"581763BR","price":45.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_6644d60d-5962-4ad4-91d9-6595f1862f11.jpg?v=1788545786","url":"https:\/\/voomisupply.com\/products\/value-collection-581763br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
