Manufactured from alloy steel with a black oxide finish, this fastener meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a reliable choice for demanding service environments. The 7\/8-9 UNC thread form and 3\/4-inch hex drive size allow for high-torque installation using standard hex keys or socket drivers. At 3 inches of length under head with full threading, this screw provides maximum thread engagement for secure clamping in a wide range of base materials.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for use in general industrial machinery, heavy equipment, fabrication work, and maintenance applications where a flush, socket-driven fastener is required. The black oxide coating provides moderate corrosion resistance and reduces light reflection, which is useful in both shop and field settings. It is commonly installed by machinists, millwrights, pipefitters, and maintenance mechanics working with steel plate, flanges, housings, or structural components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC thread size for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003e3 inches length under head, fully threaded for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex drive size for high-torque installation\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for moderate corrosion resistance and low-glare appearance\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 for use in standard inch-series tapped holes with 7\/8-9 UNC thread form, typical of heavy-duty mechanical assemblies requiring ASME\/ANSI B18.3 socket head cap screw dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanics or tradespeople using a calibrated torque wrench and the appropriate 3\/4-inch hex key or socket driver. Ensure the mating tapped hole is clean, properly sized, and free of debris before installation. Apply thread lubricant or anti-seize as required by the assembly specification to achieve accurate clamp load. Follow applicable industry torque guidelines for 7\/8-9 alloy steel fasteners per the governing engineering specification.\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\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: 6.57 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: 015503BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717418254642,"sku":"015503BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/943a39259ca9c5c44f47972029f523c3.jpg?v=1788540105","url":"https:\/\/voomisupply.com\/products\/value-collection-015503br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
