Sized at 1-8 thread with a 3.5-inch length under head, this fastener is partially threaded and conforms to ASME B18.2.1 standards. It is manufactured from Grade 8 steel, which is rated for demanding load and shear applications where lower-grade fasteners would be inadequate. The uncoated finish makes it suitable for environments where a secondary coating or plating will be applied post-installation. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener class.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in heavy-duty bolted joint assemblies across manufacturing, construction, and equipment maintenance settings. The partial threading supports clamping force distribution across unthreaded grip length, making it appropriate for applications with specific shear load requirements. The UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes. Sold in a package quantity of 10, this fastener suits both production and service applications where consistent Grade 8 performance is required across multiple joint points.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction rated for high-tensile and high-shear load requirements\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for controlled clamping and shear load distribution\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard for compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional and tolerance standards\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for post-installation plating or coating processes\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 10 for multi-point assembly applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard inch-series UNC nuts and tapped holes accepting a 1-8 thread pitch in Grade 8 or compatible high-strength bolted joint assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHex head cap screws in this size and grade are typically installed by millwrights, maintenance mechanics, or structural technicians using standard hex wrenches or impact tools. Always ensure the mating nut or tapped hole matches the UNC 1-8 thread specification before installation. Verify that the joint material and design can accommodate Grade 8 fastener preload to avoid crushing or yielding softer components. Follow applicable torque guidelines from the joint designer or relevant industry standards for the specific application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.5 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\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\u003eFinish Coating\u003c\/strong\u003e: Uncoated\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: 10\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: 99220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691815436594,"sku":"99220","price":64.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba93d4137a42e846813f6fefb5e32e51.jpg?v=1788290064","url":"https:\/\/voomisupply.com\/products\/value-collection-99220-hex-head-cap-screw-grade-8-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
