Manufactured from Grade 8 steel with a bright uncoated finish, this fastener is designed for high-strength bolted connections where superior tensile and proof load ratings are required. The partial threading configuration positions the unthreaded shank in the shear plane of the joint, which is a common engineering requirement in structural and industrial assemblies. At 5.81 pounds, this is a large-format fastener handled by millwrights, mechanical contractors, and heavy equipment maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for demanding industrial, OEM, and MRO applications where inch-series UNF fasteners are specified. Typical installation scenarios include machinery frames, heavy fabrications, structural bolted connections, and equipment bases where Grade 8 minimum hardware is called out by the design engineer or maintenance specification. The 10-inch under-head length accommodates thick material stacks or long-reach clamping applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high-strength, high-torque bolted joints\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-12 UNF thread form for fine-pitch engagement and reduced loosening under vibration\u003c\/li\u003e\n  \u003cli\u003e10-inch length under head accommodates thick material stacks and long-reach assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank keeps the unthreaded portion in the shear plane where required\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — specify additional coating or plating separately if corrosion protection is needed\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standard for inch hex cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in inch-series bolted assemblies specifying a 1-1\/2-12 UNF Grade 8 hex cap screw per ASME B18.2.1.

Always clean and inspect mating threads before assembly, and use calibrated torque equipment appropriate for Grade 8 hardware at this diameter. The hex drive requires a 2-1\/4-inch hex wrench or socket. Do not weld to or heat-treat this fastener after installation, as doing so will compromise the Grade 8 mechanical properties.\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\/2-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 10 inches\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: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.81 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 451100BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712149356850,"sku":"451100BR","price":93.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_0392f5fa-3fc5-43b5-8f83-9b1ed689c97f.jpg?v=1788484473","url":"https:\/\/voomisupply.com\/products\/value-collection-451100br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
