It carries a 7\/8-9 UNC thread profile and measures 5 inches in length under the head, with partial threading along the shank. The drive is a 3\/4-inch internal hex (Allen) socket. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and the tensile strength required for heavy-duty bolted joints. This fastener meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for precision-fit assemblies where torque retention and dimensional consistency matter.\u003c\/p\u003e\u003cp\u003eThis screw is suited for industrial, commercial, and heavy mechanical applications where a flush or low-profile cap screw head is required. Typical uses include machinery frames, hydraulic component mounting, die and fixture assembly, and general structural bolting where UNC-threaded connections are specified. The partially threaded shank provides a bearing surface that can improve joint clamping in through-bolt configurations. Machinists, millwrights, maintenance technicians, and mechanical contractors are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003e5-inch length under head with partial threading for improved shank bearing in bolted joints\u003c\/li\u003e\n\u003cli\u003e3\/4-inch internal hex drive accepts standard Allen and hex-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 provides mild corrosion resistance and reduces galling during installation\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and IFI 124 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or new-installation fastener for any application specifying a 7\/8-9 UNC hex socket cap screw per ASME\/ANSI B18.3 dimensional requirements.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/4-inch hex key or socket driver capable of handling the torque loads associated with 7\/8-inch diameter alloy steel fasteners. Ensure the mating tapped hole is clean, properly sized to 7\/8-9 UNC, and free of debris before threading. Apply thread lubricant or anti-seize compound as appropriate for the joint material and service environment. Follow applicable torque specifications from the equipment manufacturer or relevant standards such as ASME PCC-1 for bolted flange joints.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 015513BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712625869106,"sku":"015513BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25a77ba6a88e459e2abf02d30c62eef3.jpg?v=1788487075","url":"https:\/\/voomisupply.com\/products\/value-collection-015513br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
