Manufactured from alloy steel with a black oxide finish, this fastener measures 12 inches in length under the head and features a 1-1\/4-7 UNC thread form with partial threading along the shank. The 7\/8-inch hex drive accepts standard hex keys and Allen-style bits. Black oxide coating provides mild corrosion resistance and reduces light reflection in finished assemblies. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for structural and mechanical assemblies where rated fastener performance is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial, mechanical, and structural applications requiring large-diameter, high-strength socket fasteners. Typical installations include heavy machinery frames, press tooling, fixture plates, die sets, and other equipment where a flush or recessed fastener head is preferred over a hex bolt head. The partial threading allows the smooth shank to bear shear loads while the threaded portion engages the mating component. Suitable for both OEM assembly and field maintenance by millwrights, machinists, and maintenance technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread size for high-load, coarse-thread engagement\u003c\/li\u003e\n  \u003cli\u003e12-inch length under head accommodates thick structural members and deep assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank handles shear loading in precision-fitted joints\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex socket drive for use with standard Allen keys or hex bit sockets\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and a non-reflective surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 1-1\/4-7 UNC coarse-thread fastener with a 12-inch length under head in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified machinists, millwrights, or maintenance technicians using a properly sized 7\/8-inch hex key or driver. Ensure mating threads are clean and free of debris before installation. De-energize and lock out all equipment before fastener service in powered machinery. Black oxide finish is not a substitute for thread lubricant in high-torque applications; apply appropriate thread lubricant per your assembly specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 12 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: 7\/8 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, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 011581BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713821770034,"sku":"011581BR","price":121.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_8a24d134-6998-4460-b9e4-ccdd6f9156f4.jpg?v=1788495270","url":"https:\/\/voomisupply.com\/products\/value-collection-011581br-hex-socket-cap-screw-1-1-4-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
