Manufactured from Grade 8 steel with a bright uncoated finish, this fastener is built for high-strength bolted connections in heavy-duty mechanical and structural assemblies. It conforms to ASME B18.2.1 dimensional standards, making it a dependable choice for applications where fastener geometry and tensile strength are critical. Installation requires a 2-1\/4 inch hex key or corresponding wrench. Machinists, millwrights, and maintenance technicians working on industrial equipment and structural steel regularly specify Grade 8 hardware of this size.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for industrial, commercial, and heavy equipment applications where high-strength UNC fasteners are required. Typical install scenarios include machinery frames, structural steel connections, agricultural equipment, and similar bolted assemblies that demand Grade 8 tensile and proof load ratings. The fully threaded configuration provides maximum thread engagement across the full grip length, which is advantageous in through-bolt and short-stack applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high-strength bolted connections\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1-1\/2-6 UNC thread form across the full 3-1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to account for in torque calculations\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e2-1\/4 inch hex key size for standard wrenching\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or new-installation fastener for any assembly specifying a 1-1\/2-6 UNC x 3-1\/2 inch fully threaded hex head cap screw meeting ASME B18.2.1 and Grade 8 strength requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, maintenance mechanics, or structural technicians using a 2-1\/4 inch open-end, box-end, or impact wrench. De-energize and lock out all equipment before removing or installing fasteners in mechanical assemblies per applicable OSHA lockout\/tagout procedures. Apply fastener torque values per the grade and thread specification called out in the engineering drawing or equipment service manual — do not estimate torque without a reference value. Inspect mating threads for damage or contamination before assembly.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully 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\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.69 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: 451057BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720169521458,"sku":"451057BR","price":24.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5153e15896238deea4616342edb42d9a.jpg?v=1788561252","url":"https:\/\/voomisupply.com\/products\/value-collection-451057br-hex-cap-screw-1-1-2-6-x-3-5in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
