Manufactured from Grade 8 steel with a bright, uncoated finish, this fastener delivers superior tensile strength compared to lower-grade alternatives. The screw measures 13 inches in length under head with a 1-8 UNC thread size and features partial threading, making it well suited for clamping thick material stacks where full threading is not required. It conforms to ASME B18.2.1 dimensional standards. A licensed contractor, millwright, or experienced tradesperson typically selects this fastener for heavy equipment, structural steel, and large machinery installations.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a wide range of trade and industrial applications including HVAC equipment mounting, structural steel connections, heavy machinery assembly, and large-bracket anchoring. The 1-8 coarse thread pitch and Grade 8 rating make it appropriate for high-load, high-torque joints where a standard Grade 5 fastener would be insufficient. The bright uncoated surface is suitable for dry or protected indoor environments. A 1-1\/2 inch hex key or appropriately sized socket wrench is required for 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\u003e1-8 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows secure clamping of thick material assemblies\u003c\/li\u003e\n  \u003cli\u003e13 inch length under head accommodates deep-reach fastening applications\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for consistent fit and interchangeability\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for use in dry or protected environments\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 compatible with any 1-8 UNC tapped hole or nut conforming to ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified mechanic, millwright, or trades professional using a 1-1\/2 inch hex socket or wrench. Always verify the mating thread is 1-8 UNC before installation to avoid cross-threading. De-energize, depressurize, or otherwise lock out any equipment before replacing or tightening structural fasteners per applicable OSHA lockout\/tagout procedures. Do not exceed the proof load of the fastener or the rated capacity of the mating material.\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: 13 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: 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: 1-1\/2 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: 3 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: 451320BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696019210546,"sku":"451320BR","price":53.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fad1d2c039415b4aca1ec26a263cfef5.jpg?v=1788339797","url":"https:\/\/voomisupply.com\/products\/value-collection-451320br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
