Manufactured from A194 Grade 2H steel with a bright uncoated finish, this nut meets the dimensional and material standards set by ASME B1.1 and ASME B18.2.2. It features a 1-3\/8-6 UNC right-hand thread with a 2B fit class, providing reliable engagement across a wide range of compatible heavy hex bolt configurations. At 1.02 pounds per unit, it is suited for heavy-duty service where standard hex nuts are not rated for the load. Trades such as structural iron workers, industrial pipefitters, and millwrights commonly specify this grade for high-temperature or high-pressure assemblies.\u003c\/p\u003e\n\u003cp\u003eThis heavy hex nut is used in structural steel construction, pressure vessel assembly, piping flanges, and industrial equipment mounting. Its A194 Grade 2H designation makes it appropriate for bolted flange joints and structural connections that require controlled hardness and elevated load capacity. The uncoated finish is suitable for applications where additional coatings or gaskets will be applied in the field or where environmental exposure is managed by the installer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA194 Grade 2H steel construction with hardness range of 24-35 HRC for high-strength bolted joints\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-6 UNC right-hand thread, 2B fit class, conforming to ASME B1.1\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile with 2-3\/16 inches across flats per ASME B18.2.2\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no plating to affect dimensional tolerance or conductivity\u003c\/li\u003e\n  \u003cli\u003eHeight of 1-11\/32 inches providing additional bearing surface versus standard hex nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-3\/8-6 UNC heavy hex bolts and threaded rod conforming to ASME B1.1 dimensional standards.

Power down or de-energize any associated systems before working on bolted connections in electrical or pressurized service. Follow the applicable fastener torque specifications from the engineering drawings or applicable code — no torque values are published here. Inspect threads for damage or contamination before assembly to ensure proper 2B fit engagement.\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: 1-3\/8-6 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 2B\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: A194 Grade 2H\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\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-11\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 24-35 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B1.1, ASME B18.2.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.02 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: 314440BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720744993074,"sku":"314440BR","price":19.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f836482da2828446a183763cb9417cd.jpg?v=1788568519","url":"https:\/\/voomisupply.com\/products\/value-collection-314440br-heavy-hex-nut-1-3-8-6-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
