Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets ASME B18.2.1 standards for dimensional accuracy and performance. It features a 1-1\/2-6 UNC thread size, a 3-inch length under head, and a 2-1\/4-inch hex key drive. At 0.05 pounds, the part is sized for high-strength connections where torque and tensile requirements exceed what lower-grade fasteners can handle. Licensed tradespeople and maintenance professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in heavy equipment assembly, machinery frames, structural steel connections, and maintenance repair operations where Grade 8 tensile strength is specified. The fully threaded design allows maximum thread engagement across the full length of the fastener, making it appropriate for shorter through-bolt applications and standard tapped-hole installations. The UNC thread form is compatible with standard inch-series tapped holes and nuts.\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 requirements\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1-1\/2-6 UNC along the full 3-inch length under head\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for use with standard hardened washers and Grade 8 nuts\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex cap screws\u003c\/li\u003e\n  \u003cli\u003e2-1\/4-inch hex drive size for use with standard open-end, box, or impact wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series Grade 8 hex head cap screw for use in any application requiring a 1-1\/2-6 UNC threaded fastener with a 3-inch length under head per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with high-strength fastener procedures. Always verify mating thread condition and use hardened Grade 8 washers and nuts rated to the same grade. Follow applicable torque specifications from the equipment manufacturer or relevant engineering standards — no torque value is supplied with this part. Do not install in applications requiring a corrosion-resistant or plated finish without first confirming compatibility with the service environment.\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: 3 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: 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 451055BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722897457458,"sku":"451055BR","price":48.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47b34c91669d2b59ebeb46cf448150c3.jpg?v=1788597561","url":"https:\/\/voomisupply.com\/products\/value-collection-451055br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
