Sized at 7\/8-9 UNC with a 7-inch length under head, this fastener is driven by a 3\/4-inch hex socket. Constructed from alloy steel and finished with a black oxide coating, it provides corrosion resistance and a consistent surface hardness. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding load-bearing connections where tensile strength and dimensional precision are required.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for heavy-duty mechanical and industrial installations where large-diameter, high-strength fasteners are specified. Typical applications include machine bases, structural frame assemblies, tooling fixtures, and equipment mounting where a recessed drive and controlled clamping force are necessary. The 7\/8-9 UNC thread pitch is commonly specified in engineering drawings for inch-standard assemblies requiring robust thread engagement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC thread size with 7-inch length under head for deep fastening reach\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a bearing surface for shear-load applications\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex drive for high-torque socket wrench installation\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated to ASTM A574 for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces surface corrosion and minimizes light reflection in service environments\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series hex socket cap screw suitable for use in any assembly specifying 7\/8-9 UNC partially threaded socket head fasteners per ASME\/ANSI B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician using a calibrated torque wrench with the appropriate 3\/4-inch hex socket bit. Always degrease and inspect the tapped hole before installation to ensure clean thread engagement. Do not exceed the engineered torque specification for the mating material as defined by the application design drawings. Follow applicable industry and facility safety standards when working with high-strength fasteners under load.\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: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 011521BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707430928690,"sku":"011521BR","price":28.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c67bdcade6bf848361c5579b16f100d.jpg?v=1788440276","url":"https:\/\/voomisupply.com\/products\/value-collection-011521br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
