Manufactured from Grade 8 steel with no finish coating applied, this fastener delivers the high tensile strength required for demanding bolted connections. With a thread size of 1-8 UNC and a length under head of 4.5 inches, it is sized for thick-section joints where a partially threaded shank provides improved shear resistance and a cleaner bearing surface between clamped parts. This screw conforms to ASME B18.2.1, the standard governing the dimensions and tolerances of inch-series hex head fasteners. Maintenance technicians, millwrights, and general contractors routinely specify this fastener type for equipment mounting, structural steel work, and heavy fabrication.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in commercial and industrial applications where high-clamp-load bolted joints are required. Typical install scenarios include machinery bases, structural steel connections, equipment frames, and heavy-bracket assemblies. The uncoated finish makes it straightforward to apply thread lubricant or anti-seize compound as required by the application. It is sold in a package quantity of 10, making it practical for small jobs or sample ordering, with a minimum order quantity of 1 package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for demanding bolted assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear resistance and allows precise clamp-load distribution\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread form is one of the most widely used coarse thread sizes in inch-series fastening\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional accuracy and interchangeability\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows direct application of thread lubricants or anti-seize compounds\u003c\/li\u003e\n  \u003cli\u003eSold in packages of 10 with a minimum order quantity of 1 package\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 with 1-8 UNC threaded nuts, tapped holes, and heavy hex hardware conforming to ASME B18.2.1 dimensional requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHex head cap screws of this size are typically installed by millwrights, ironworkers, or maintenance mechanics using a heavy-duty impact wrench or box-end wrench. Always verify the mating tapped hole or nut is rated for Grade 8 fastener loads before assembly. Apply thread lubricant or anti-seize compound as required by the joint specification. Do not mix Grade 8 fasteners with lower-grade nuts, as mismatched hardware can result in thread stripping or joint failure.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 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\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\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: 99222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691578294578,"sku":"99222","price":84.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c28eb2d4d9e32575ba55f00249d822d4_ae895f5f-c667-4c83-ae1f-c733f670f39e.jpg?v=1788287261","url":"https:\/\/voomisupply.com\/products\/value-collection-99222-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
