It features a 7\/8-9 UNC thread form and measures 10 inches in length under the head, making it well suited for through-bolting thick structural members, machinery frames, and fabricated assemblies. The fastener is manufactured from Grade 2 steel with a zinc-plated finish that provides a basic level of corrosion resistance in dry or mildly humid environments. The 1-5\/16 inch hex drive size is compatible with standard commercial hex wrenches and impact sockets. Machinists, millwrights, pipefitters, and general maintenance technicians are the typical installers of this fastener.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for light-to-moderate structural and mechanical fastening tasks in residential and commercial settings. Partial threading allows the unthreaded shank to bear shear loads while the threaded section engages a nut or tapped hole. Typical applications include equipment mounting, structural steel connections, conveyor frames, and general fabrication work where a standard hex head and UNC thread form are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread form for compatibility with standard unified coarse-thread nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e10-inch length under head accommodates thick material stacks and deep through-bolt installations\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear load performance at the joint interface\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance in dry and mildly humid environments\u003c\/li\u003e\n  \u003cli\u003e1-5\/16 inch hex drive compatible with standard commercial sockets and open-end wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 7\/8-9 UNC hex head cap screw conforming to ASME B18.2.1, this fastener is compatible with any application specifying a Grade 2 steel, partially threaded hex cap screw in that thread size and 10-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by maintenance technicians, millwrights, or general contractors using a torque wrench or impact driver fitted with the appropriate hex socket. Always match the nut or tapped hole to the 7\/8-9 UNC thread specification before installation. Apply a thread lubricant or anti-seize compound where specified by the equipment manufacturer to achieve accurate clamp load from torque. Follow applicable industry standards and equipment manufacturer guidelines for proper fastener 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: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.84 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\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: R52001293\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700586250546,"sku":"R52001293","price":27.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/664010c3b54f91e610b56b42735d85f8.jpg?v=1788392330","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001293-hex-head-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
