It is partially threaded and carries an uncoated, bright finish. Designed to meet ASME B18.2.1 standards, this fastener delivers the high tensile strength required for heavy-duty structural and mechanical assemblies. It is installed using a 15\/16-inch hex key or wrench. Trades professionals across industrial, mechanical, and construction applications rely on Grade 8 hardware when joint integrity under load is critical.\u003c\/p\u003e\n\u003cp\u003eThis cap screw suits applications that demand a high-strength inch-series fastener in larger diameter and longer length configurations. Typical install scenarios include steel fabrication, heavy equipment assembly, structural bolting, and mechanical component mounting where partial threading is preferred to allow for proper clamping in thicker material stacks. The bright, uncoated finish is appropriate for dry or protected interior environments where corrosion exposure is limited.\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\u003e5\/8-11 UNC thread size with 12-inch length under head for deep fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows full clamping force across thick material stacks\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for inch-series hex head cap screws\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for controlled environments\u003c\/li\u003e\n  \u003cli\u003e15\/16-inch hex drive for standard wrench and socket tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener for applications requiring a 5\/8-11 UNC Grade 8 hex head cap screw with a 12-inch length under head per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical trades using standard socket or open-end wrenches sized at 15\/16 inches. Always de-energize or fully isolate any equipment being disassembled before removing or replacing structural fasteners. Follow applicable torque guidelines per the joint design specification for Grade 8 hardware. Inspect threads for damage before installation and ensure mating threads are clean and free of debris.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 12 inches\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\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: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 451166BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689696821554,"sku":"451166BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e5f2cfdc8b2cfc80e3a2812b86a325f.jpg?v=1788263161","url":"https:\/\/voomisupply.com\/products\/value-collection-451166br-hex-head-cap-screw-5-8-11x12-g8","provider":"Voomi Supply","version":"1.0","type":"link"}
