Manufactured from Grade 8 steel in an uncoated finish, this fastener measures 1-8 thread size with a 3-1\/4 inch length under head and features partial threading along the shank. It conforms to ASME B18.2.1 and SAE J429 standards, making it a reliable choice where dimensional and strength compliance are required. Installed by millwrights, pipefitters, electricians, and general mechanical contractors, this screw is suited for structural and mechanical assemblies that demand consistent load-bearing performance.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used in a wide range of industrial, commercial, and mechanical installation scenarios. Its Grade 8 rating indicates a minimum tensile strength of 150,000 psi, making it appropriate for high-stress bolted connections in equipment mounting, structural steel fabrication, machinery assembly, and similar demanding applications. The partial threading allows the unthreaded shank to bear shear loads, a common requirement in precision-fit or close-tolerance joint designs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank accommodates shear-load bearing joint designs\u003c\/li\u003e\n  \u003cli\u003eUNC (Unified National Coarse) thread standard for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications where post-installation coating or paint will be applied\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 10 for efficient stocking and use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard UNC hex nuts and tapped holes sized for a 1-8 thread, consistent with ASME B18.2.1 and SAE J429 compliant fastener systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanical, structural, or maintenance trades using standard hex-drive hand tools or power tools rated for the fastener size. Always verify the mating nut or tapped hole is rated to Grade 8 or equivalent to avoid fastener-joint mismatch. Consult applicable structural or equipment codes before finalizing torque and clamp-load requirements. Inspect threads for damage before installation and do not use with cross-threaded or undersized holes.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-1\/4 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\u003c\/strong\u003e: Uncoated\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\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: KP45647\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710822678834,"sku":"KP45647","price":68.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12fc6c9d739a75896a56bed03c6401af.jpg?v=1788471010","url":"https:\/\/voomisupply.com\/products\/value-collection-kp45647-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
