Sized at 7\/8-9 UNC thread with an 11-inch length under the head, this fastener is manufactured from 18-8 stainless steel and left uncoated, making it well suited for environments exposed to moisture, chemicals, or outdoor conditions. The 7\/8-9 designation indicates a 7\/8-inch nominal diameter with 9 threads per inch on a Unified National Coarse thread form. Licensed trades and industrial maintenance technicians use fasteners in this class for structural, mechanical, and equipment-mounting work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in industrial, commercial, and heavy mechanical applications where a large-diameter, long-length fastener is needed. The partially threaded shank provides a smooth bearing surface through the grip area, which is useful when clamping two or more members together without thread engagement in the shank zone. Typical applications include equipment frames, structural assemblies, pump and motor mounting, and similar trade and industrial installations requiring corrosion-resistant hardware.\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 inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e11-inch length under head provides a long grip length for thick structural members\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and chemically active environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank delivers a smooth bearing surface through the grip zone\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains base material properties without added plating or treatment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 7\/8-9 UNC inch-series hex nuts, flat washers, and lock washers in industrial and mechanical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of large-diameter cap screws in this size range typically requires a proper-sized combination or socket wrench and should follow applicable torque specifications for 18-8 stainless steel fasteners, as stainless hardware is prone to galling without proper lubrication. Apply an anti-seize compound to the threads before assembly to reduce the risk of thread galling and seizure. Always verify that the mating nut or tapped hole matches the 7\/8-9 UNC thread specification before driving the fastener.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: R88448908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712132579634,"sku":"R88448908","price":53.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b7a553af274a2d3a57b5b7b5f52c8dc.jpg?v=1788484177","url":"https:\/\/voomisupply.com\/products\/value-collection-r88448908-hex-head-cap-screw-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
