Manufactured from Grade 8 steel with no coating applied, this fastener measures 7\/8-9 thread size with a 3-inch length under head and follows the Unified National Coarse (UNC) thread standard. The shank is partially threaded, which provides a bearing surface in the unthreaded zone for shear-loaded joints. Compliance with ASME B18.2.1 and SAE J429 confirms dimensional and mechanical property conformance to recognized industry standards. Installers and maintenance professionals in mechanical, structural, and industrial settings rely on Grade 8 fasteners where standard hardware-grade bolts are insufficient.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for structural assemblies, heavy equipment, agricultural machinery, and industrial fabrication where high-clamp-load connections are required. The partially threaded shank makes it a common choice in bolted joints where the grip length must extend through unthreaded material. Packaged in quantities of 25, it is appropriate for shop stock, field service kits, or production line use. Minimum order quantity is 1 package of 25.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread size, partially threaded shank\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head for use in thick-section joints\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for applications where additional plating or treatment will be applied, or where coating is not required\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards and SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 25 with a minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC hex head cap screw for use in any application requiring a 7\/8-9 threaded fastener with a 3-inch grip length.

Always confirm hole alignment and grip length before final tightening. Consult the applicable engineering specification or torque table for the correct tightening value for this thread size and grade. Do not reuse fasteners that have been torqued to yield or show signs of thread damage.\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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 99198\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718298468658,"sku":"99198","price":97.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/467fe9729f2eb6aba7c4a1864d53109c.jpg?v=1788551776","url":"https:\/\/voomisupply.com\/products\/value-collection-99198-hex-head-cap-screw-7-8-9-x-3-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
