It carries a 1-1\/4-7 UNC thread and an 18-inch length under the head, making it suited for deep-reach or heavy-section clamping applications. The screw is partially threaded, which maintains shank strength across the unthreaded portion of the grip length. Drive engagement is through a 7\/8-inch hex socket. Construction is alloy steel with a black oxide finish, meeting ASME\/ANSI B18.3 and ASTM A574 standards. Licensed tradespeople and maintenance machinists working on structural, industrial, or heavy equipment fastening applications typically install this fastener.\u003c\/p\u003e\n\u003cp\u003eThis screw fits heavy industrial, manufacturing, and mechanical assembly environments where large-diameter socket cap screws are specified. The 1-1\/4-7 UNC coarse thread is common in steel-to-steel joints, machine bases, fixtures, and structural frames. The partial threading pattern is preferred when the joint requires a precise grip length or when the shank must pass through a clearance hole before engaging the tapped bore. The black oxide coating provides mild corrosion resistance and reduces galling during installation in metal-to-metal contact conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for high-load, steel-to-steel applications\u003c\/li\u003e\n  \u003cli\u003e18-inch length under head for deep-reach or thick-section clamping\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank maintains grip-length shank strength\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex socket drive for standard hex key or socket tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces surface galling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or replacement fastener for industrial machinery, structural frames, and heavy equipment assemblies that specify 1-1\/4-7 UNC hex socket cap screws conforming to ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician using a calibrated torque wrench and the correct 7\/8-inch hex key or drive socket. De-energize and lock out all energy sources on the equipment before fastener removal or replacement. Verify thread engagement depth and hole condition before driving; do not force the screw into a misaligned or damaged tapped bore. Follow applicable industry torque tables for ASTM A574 alloy steel socket cap screws when determining final torque values.\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: 18 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 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\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: 581196BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51734982099250,"sku":"581196BR","price":87.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d4d25990b26a9165e87734f7577bbc8.jpg?v=1788768869","url":"https:\/\/voomisupply.com\/products\/value-collection-581196br-hex-socket-cap-screw-1-1-4-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
