It features a 1-1\/8-7 UNC thread size, a 2.5-inch length under head, and a 7\/8-inch hex drive socket. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and durability under load. The fully threaded shank maximizes thread engagement throughout the grip length, making it a reliable choice for structural and machine assembly work.\u003c\/p\u003e\u003cp\u003eThis screw suits a wide range of industrial, manufacturing, and maintenance applications where high tensile strength fasteners are required. The 1-1\/8-7 UNC coarse thread pitch is well suited for use in steel and heavy-gauge metal assemblies. The black oxide coating reduces surface friction and provides mild corrosion protection, making this screw appropriate for both indoor and controlled outdoor service environments where a non-reflective finish is preferred.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/8-7 UNC coarse thread for strong thread engagement in steel and metal substrates\u003c\/li\u003e\n\u003cli\u003eFully threaded shank maximizes grip and clamping force\u003c\/li\u003e\n\u003cli\u003e7\/8-inch hex socket drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile strength per ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating offers mild corrosion resistance and a non-reflective finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style or aftermarket replacement hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574 standards, suitable for use in applications requiring a 1-1\/8-7 UNC coarse-thread alloy steel cap screw.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by maintenance technicians, millwrights, or mechanical assemblers using a calibrated torque wrench with a 7\/8-inch hex bit or key. Ensure mating threads are clean, free of debris, and properly tapped to 1-1\/8-7 UNC specification before installation. Apply thread lubricant or anti-seize compound as required by the application. Follow applicable ASME or equipment manufacturer torque specifications for the fastener grade and joint material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-7 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 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: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.93 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: 581863BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696434708786,"sku":"581863BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_0e930b30-6708-4c18-8181-cada0b3b05ec.jpg?v=1788342645","url":"https:\/\/voomisupply.com\/products\/value-collection-581863br-hex-socket-cap-screw-1-1-8-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
