It features a 1-1\/8-7 UNC thread size and a 5-1\/2 inch length under head, providing substantial grip for heavy-duty connections. The 7\/8 inch hex drive socket interface allows torque application with a standard hex key or Allen wrench. Constructed from alloy steel with a black oxide finish coating, this fastener resists corrosion and surface wear under demanding service conditions. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming dimensional and mechanical compliance for safety-critical installations.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is suited for machinery assembly, industrial equipment mounting, fixture fabrication, and general structural fastening where a recessed drive and high clamping load are required. The partial thread design concentrates clamping force and provides a smooth shank section, making it appropriate for clearance hole applications and shear-loaded joints. Machinists, millwrights, maintenance mechanics, and fabricators typically install this fastener in production and field service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread for high-load fastening in standard unified coarse applications\u003c\/li\u003e\n  \u003cli\u003e5-1\/2 inch length under head accommodates thick material stackups\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides a shank section for shear resistance and precise hole alignment\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch hex socket drive allows high-torque installation with standard tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers superior tensile and yield strength over carbon steel alternatives\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish coating reduces surface corrosion and minimizes light reflection in industrial settings\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 standards for dimensional accuracy and mechanical performance\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\/8-7 UNC partially threaded fastener with a 7\/8 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance mechanics using a calibrated torque wrench and a 7\/8 inch hex key or bit. De-energize and lock out equipment before fastener installation or removal in accordance with applicable OSHA lockout\/tagout procedures. Verify mating thread condition and clearance hole diameter before assembly. Do not substitute a fastener of lower grade or different thread specification in applications governed by engineered drawings or equipment manufacturer requirements.\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\/8-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5-1\/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 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\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.93 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: 581875BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698841452850,"sku":"581875BR","price":17.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_0ff299c1-af54-4f2b-b1e4-88449d6a966c.jpg?v=1788368760","url":"https:\/\/voomisupply.com\/products\/value-collection-581875br-hex-socket-cap-screw-1-1-8-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
