With a 1-1\/2-6 UNC thread and a 5-1\/2-inch length under head, this fastener is built from Grade 8 steel and left uncoated with a bright finish. It is partially threaded, conforming to ASME B18.2.1 dimensional standards. Weighing 3.65 pounds, it is sized for large-scale bolted connections where tensile and shear strength requirements are critical. Machinists, millwrights, and structural ironworkers are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy equipment assembly, structural steel fabrication, agricultural machinery, and industrial maintenance applications where Grade 8 strength is required. The 1-1\/2-6 UNC coarse thread pitch is standard in large-diameter fastener applications and mates with corresponding Grade 8 nuts and threaded assemblies. Partial threading is appropriate for through-bolt installations where grip length and shank clearance are necessary for proper joint clamping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength in demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-6 UNC coarse thread for compatibility with standard large-diameter threaded hardware\u003c\/li\u003e\n  \u003cli\u003e5-1\/2-inch length under head accommodates thick structural members and stacked assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides proper grip length and bearing surface for bolted joints\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with supplemental coatings or in controlled environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension hex head cap screw per ASME B18.2.1, compatible with Grade 8 heavy hex nuts and hardened washers in 1-1\/2-6 UNC thread configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified millwrights, ironworkers, or maintenance mechanics familiar with high-strength bolted joint procedures. Always use a calibrated torque wrench and apply the correct torque per the applicable structural or equipment specification. Pair with hardened flat washers and Grade 8 nuts to maintain joint integrity. Do not reuse fasteners that have been subjected to yield-level loading or visible deformation.\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\/2-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.65 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 451063BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704619204914,"sku":"451063BR","price":31.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_24ef0b86-9922-4714-8696-ef33b04cfa06.jpg?v=1788423873","url":"https:\/\/voomisupply.com\/products\/value-collection-451063br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
