Manufactured from Grade 8 steel with an uncoated finish, this fastener meets ASME B18.2.1 standards for inch-series hex cap screws. The thread size is 1-1\/4-7 UNC with a length under head of 9-1\/2 inches, making it suited for thick structural connections and heavy equipment joints. Maintenance technicians, millwrights, and industrial mechanics working with large-diameter hardware will recognize this fastener as a standard Grade 8 heavy hex application component.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is intended for use in structural, mechanical, and industrial applications where high-strength fastening is required. The 1-1\/4-7 UNC thread pitch is the standard coarse thread designation for this diameter, offering good resistance to cross-threading and ease of assembly in typical field conditions. The partial threading configuration allows for shank engagement across joint interfaces, which is common in bolted connections on equipment frames, machinery bases, and heavy structural assemblies. This fastener is sold in a package quantity of 2.\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\u003ePartially threaded shank provides shear load capacity across the joint\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for reliable field assembly\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for applications where a coating is not required or where the installer applies their own treatment\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for inch-series hex cap screws\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 2 per order unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in heavy structural and mechanical bolted connections requiring a 1-1\/4-7 UNC thread and 9-1\/2 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of large-diameter Grade 8 fasteners should be performed by qualified millwrights or mechanics using calibrated torque tooling appropriate for the fastener size and joint design. Always verify mating thread condition before assembly and use the specified torque value from the equipment manufacturer or applicable engineering standard. Do not mix Grade 8 fasteners with lower-grade nuts or mating hardware. Uncoated fasteners exposed to corrosive environments may require the application of an appropriate coating or lubricant per the installation specification.\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\/4-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 9-1\/2 inches\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 Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\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: 99255\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693211812146,"sku":"99255","price":79.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df20a9ee13d4377736bcdeb92addfb79.jpg?v=1788309030","url":"https:\/\/voomisupply.com\/products\/value-collection-99255-hex-head-cap-screw-grade-8-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
