Heavy hex nuts carry a wider, thicker profile than standard hex nuts, distributing clamping load across a larger bearing surface. This makes them a common choice in structural, industrial, and mechanical assemblies where fastener integrity under sustained load is required. The right-hand thread engages standard 1-1\/2-6 UNC threaded rod, bolts, and studs. Licensed tradespeople including millwrights, pipefitters, ironworkers, and general contractors install these in both new construction and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis nut is suited for use in heavy structural connections, equipment mounting, flange assemblies, and general industrial fastening where a coarse-thread, large-diameter nut is required. The Grade 2 material designation indicates low to medium carbon steel, appropriate for non-critical structural and mechanical applications where high-strength alloy hardware is not specified. The bright uncoated finish is standard for interior or protected environments. No additional plating or coating is applied, so installations in corrosive or outdoor environments may require supplemental protection or a different finish grade.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy hex profile with 2-3\/8 inch width across flats for increased bearing surface\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-6 UNC right-hand thread for compatibility with standard coarse-thread fastener systems\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose structural and mechanical use\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no plating or surface treatment applied\u003c\/li\u003e\n  \u003cli\u003eHeight of 1.4688 inches provides substantial thread engagement depth\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications — intended for commercial and industrial applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-1\/2-6 UNC threaded fasteners including bolts, studs, and threaded rod in general industrial, structural, and mechanical assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with fastener torque requirements for the applicable assembly and material. Always verify thread engagement depth and ensure mating fastener thread specification matches 1-1\/2-6 UNC before tightening. Use appropriate wrenches sized for a 2-3\/8 inch across-flats dimension. For outdoor or corrosive environments, evaluate whether an uncoated finish is appropriate for the service condition before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Heavy Hex Nut\u003c\/li\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.4688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161727\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: 318420BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700421689650,"sku":"318420BR","price":27.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d32fca6105d0bf4959dc7905832da7a9.jpg?v=1788390139","url":"https:\/\/voomisupply.com\/products\/value-collection-318420br-heavy-hex-nut-1-1-2-6-unc-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
