Manufactured from alloy steel with a black oxide coating, this fastener delivers reliable clamping force and corrosion resistance in demanding environments. The 7\/8-inch hex drive accepts a standard hex key or socket driver, and the 6-1\/2-inch length under head provides deep engagement in thick material stacks. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming dimensional accuracy and mechanical property requirements expected by professional tradespeople and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machinery maintenance, equipment assembly, and heavy fabrication work where a flush or recessed fastener head is required. The 1-1\/4-7 UNC coarse thread pattern is common in general industrial fastening, offering strong pull-out resistance in steel and ductile iron applications. The partial threading allows the unthreaded shank to act as a shoulder, providing precise alignment in close-tolerance bores. It is typically installed by millwrights, maintenance mechanics, and industrial technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements for high-strength socket cap screws\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for strong engagement in steel and ductile iron tapped holes\u003c\/li\u003e\n  \u003cli\u003e6-1\/2-inch length under head accommodates deep material stacks and thick flanges\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex drive accepts standard hex keys and socket drive tools\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank assists alignment and functions as a shoulder in close-tolerance bores\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for industrial machinery, structural assemblies, and equipment requiring a 1-1\/4-7 UNC high-strength socket cap screw per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights or maintenance mechanics using a calibrated torque wrench with a 7\/8-inch hex bit. Verify that the tapped hole thread form and depth meet ASME\/ANSI B18.3 requirements before installation. Clean and inspect the bore for damage or contamination prior to fastener insertion. Apply thread lubricant or anti-seize compound as specified by the equipment manufacturer to achieve accurate clamp load.\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: 6-1\/2 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: 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\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 011571BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695913763122,"sku":"011571BR","price":80.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_7f1f8d8e-c1f0-4a90-bd16-ab70908c7bb3.jpg?v=1788339335","url":"https:\/\/voomisupply.com\/products\/value-collection-011571br-hex-socket-cap-screw-1-1-4-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
