It is partially threaded and left uncoated (bright finish), conforming to ASME B18.2.1 dimensional standards. Grade 8 fasteners deliver high tensile strength for demanding structural and mechanical assemblies. This screw is driven with a 1.5-inch hex key and is suited for heavy-duty bolted joints in industrial, agricultural, and mechanical equipment applications. Machinists, millwrights, and maintenance technicians are the primary installers of fasteners in this class.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is intended for use in high-load, vibration-prone bolted connections where Grade 8 tensile strength is specified. The 1-14 UNF thread form provides finer thread engagement than coarse-thread equivalents, making it well suited for precision clamping applications and situations where controlled preload is critical. The uncoated bright finish is appropriate for indoor or protected environments and for assemblies where secondary coating or plating will be applied after installation.\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\u003e1-14 UNF thread form for fine thread engagement and controlled preload\u003c\/li\u003e\n  \u003cli\u003e6.5-inch length under head accommodates deep or thick-stack assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows bearing-surface clamping without thread engagement through the full grip length\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish meets ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eDriven with a 1.5-inch hex wrench for positive, high-torque installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or MRO replacement hex head cap screw for heavy-duty bolted assemblies requiring a 1-14 UNF Grade 8 fastener conforming to ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, machinist, or maintenance technician familiar with high-strength fastener torque requirements. Power down and de-energize or depressurize any equipment before disassembling bolted joints. Use a calibrated torque wrench and consult the applicable equipment manufacturer torque specification for Grade 8 fasteners of this diameter and thread pitch before tightening. Avoid mixing Grade 8 fasteners with lower-grade nuts or flanges not rated for the corresponding load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-14 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 Coating\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1.5 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 pounds\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: 451191BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703087628594,"sku":"451191BR","price":32.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bddf2a7deb8353f235f0f1e2658ff728.jpg?v=1788414732","url":"https:\/\/voomisupply.com\/products\/value-collection-451191br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
