It features a 1-1\/8-7 UNC thread size and an 11-inch length under the head, making it suitable for deep-reach clamping and bolted joint applications. The alloy steel construction is finished with a black oxide coating that provides a degree of corrosion resistance and reduces light reflection in service environments. A 7\/8-inch hex drive socket is required for installation. Licensed mechanics, millwrights, and industrial maintenance technicians typically install fasteners of this type.\u003c\/p\u003e\u003cp\u003eThis screw is well suited for structural, machine, and tooling assemblies that demand a large-diameter, partially threaded socket cap screw. The coarse 7 UNC thread pitch provides strong clamping force and is easier to start in tapped holes compared to fine-thread variants. The black oxide finish makes this fastener a common choice in manufacturing fixtures, heavy equipment, and general industrial machinery where appearance and moderate corrosion protection are both factors.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/8-7 UNC coarse thread for strong engagement and easy installation in tapped alloy steel holes\u003c\/li\u003e\n\u003cli\u003e11-inch length under head accommodates deep clamping and long-reach fastening applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a bearing surface for precise joint alignment\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards for socket cap screws\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating offers mild corrosion resistance and a low-reflectance finish\u003c\/li\u003e\n\u003cli\u003e7\/8-inch hex drive socket interface for high-torque installation with standard drive tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 socket cap screw for use in any application requiring a 1-1\/8-7 UNC partially threaded fastener with an 11-inch grip length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright using a 7\/8-inch hex drive socket and an appropriate torque wrench. Ensure the mating tapped hole is clean, properly formed to 1-1\/8-7 UNC specification, and free of debris before threading the screw. De-energize and lock out any machinery before servicing fasteners on live equipment in accordance with applicable OSHA lockout\/tagout procedures. Do not substitute this screw for a different thread class or grade without verifying joint design requirements.\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: 11 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\u003eWeight\u003c\/strong\u003e: 0.01 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: 581055BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723531813170,"sku":"581055BR","price":40.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_aed61756-c907-441c-818f-e3a12ca49aeb.jpg?v=1788605891","url":"https:\/\/voomisupply.com\/products\/value-collection-581055br-hex-socket-cap-screw-1-1-8-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
