It features a 1-1\/8-7 UNC thread size and a 16-inch length under head, making it suited for deep-reach clamping and through-bolting scenarios. Manufactured from alloy steel with a black oxide finish, this screw delivers strong corrosion resistance and surface hardness. The 7\/8-inch hex drive accepts standard hex keys and socket drivers. It meets ASME\/ANSI B18.3 and ASTM A574 dimensional and mechanical standards. Machinists, millwrights, maintenance technicians, and industrial assembly crews are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy-duty mechanical assemblies where a recessed drive head and high tensile strength are required. Typical applications include machine frames, jigs and fixtures, press assemblies, and structural steel connections. The partially threaded shank provides a smooth bearing surface in clearance holes, which is important for shear-loaded joints. At 16 inches in length, this fastener is well suited for thick-section clamping or through-bolting in fabricated steel structures and large mechanical components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread for high-load coarse-thread engagement in standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e16-inch length under head accommodates deep-reach and thick-section fastening\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a smooth bearing surface for shear-loaded joints\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 glare\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex socket drive accepts standard hex keys and socket drive tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex socket cap screw for use in any 1-1\/8-7 UNC tapped hole or clearance-drilled assembly requiring an ASME\/ANSI B18.3 compliant fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or maintenance technicians familiar with inch-series fastener standards. Ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench with the appropriate 7\/8-inch hex socket or hex key bit and torque to values specified in the applicable engineering documentation for ASTM A574 alloy steel fasteners. De-energize and lock out any machinery before servicing fastened assemblies per OSHA lockout\/tagout 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: 16 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 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 581067BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699207405874,"sku":"581067BR","price":62.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_9051e4d6-02a7-47b5-977e-4d444ca8d768.jpg?v=1788373529","url":"https:\/\/voomisupply.com\/products\/value-collection-581067br-hex-socket-cap-screw-1-1-8-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
