It features a 7\/8-9 UNC thread size with a 6-inch length under head, manufactured from alloy steel with a black oxide finish that provides mild corrosion resistance and reduces light reflection on exposed hardware. The 3\/4-inch hex drive accepts a standard hex key or Allen wrench. This fastener meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a recognized choice for precision and load-bearing connections.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for general industrial maintenance, machine assembly, tooling fixtures, and structural fastening where a socket drive is preferred over a hex head. The coarse UNC thread pattern allows for faster installation and is well-suited to applications involving lower-strength base materials or situations requiring frequent removal and reinstallation. Machinists, millwrights, maintenance technicians, and mechanical contractors commonly specify this fastener type across a broad range of equipment and fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC coarse thread for reliable engagement and faster assembly\u003c\/li\u003e\n\u003cli\u003e6-inch length under head accommodates thicker stock and deep-reach applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a stronger grip zone and better shear resistance\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength socket cap screw requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion protection and low-reflectance appearance\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex drive compatible with standard hex keys and socket drive tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-specification hex socket cap screw per ASME\/ANSI B18.3 and ASTM A574 for use in any application requiring a 7\/8-9 UNC coarse-thread socket cap screw with a 6-inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with fastener torque specifications appropriate for the base material and joint design. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or anti-seize compound as required by the application to prevent galling in alloy-to-alloy contact. Always follow applicable mechanical codes and equipment manufacturer guidelines when specifying fastener torque values.\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: 6 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 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, IFI 124\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.5 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: 015517BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721180315954,"sku":"015517BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1356bca6871c5f29cba59a485e1811c0.jpg?v=1788574809","url":"https:\/\/voomisupply.com\/products\/value-collection-015517br-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
