This nut is designed for high-strength bolted assemblies where consistent clamping force and dimensional reliability are required. The 2H designation indicates a heavy hex geometry with controlled hardness in the 24 to 35 HRC range, making it suitable for structural, pressure vessel, and industrial pipe flange applications. It measures 2-3\/16 inches across the flats and 1-11\/32 inches in height, conforming to ASME B1.1 and ASME B18.2.2 standards. Mechanical contractors, pipefitters, and structural ironworkers will encounter this nut in heavy bolting scenarios.\u003c\/p\u003e\u003cp\u003eThis heavy hex nut is used in industrial and commercial applications where high-strength fastening is required, including pressure vessel assemblies, structural steel connections, and large-diameter piping flanges. The right-hand thread direction and 2B thread fit class allow straightforward pairing with standard UN-threaded bolts and studs in the 1-3\/8-8 size range. It is sold individually and is appropriate for both new construction and maintenance and repair operations in heavy industrial environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA194 Grade 2H steel construction for high-strength, controlled-hardness performance\u003c\/li\u003e\n\u003cli\u003eHardness range of 24 to 35 HRC for consistent mechanical properties\u003c\/li\u003e\n\u003cli\u003e2-3\/16 inches across flats and 1-11\/32 inches in height per ASME B18.2.2\u003c\/li\u003e\n\u003cli\u003eRight-hand thread, 2B fit class, conforming to ASME B1.1 UN thread standard\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with standard lubricants or thread compounds\u003c\/li\u003e\n\u003cli\u003eIndividually packaged with no minimum order beyond a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-3\/8-8 UN-threaded bolts and studs in heavy hex fastening applications conforming to ASME B18.2.2 dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanical contractor, pipefitter, or ironworker familiar with ASME and AISC torque and tensioning requirements for heavy hex fasteners. Always de-energize or depressurize the system before disassembling or replacing fasteners in pressurized or structural assemblies. Apply an appropriate thread lubricant or anti-seize compound per the project specification to achieve accurate clamp load. Do not use impact tools without a controlled torque method, and verify thread engagement meets minimum depth requirements before loading the joint.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\/8-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 314450BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712174948658,"sku":"314450BR","price":19.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/339d7c7e80b3eb5d9cbca9018e962a6e.jpg?v=1788484690","url":"https:\/\/voomisupply.com\/products\/value-collection-314450br-heavy-hex-nut-1-3-8-8","provider":"Voomi Supply","version":"1.0","type":"link"}
