Heavy hex nuts are dimensionally larger across the flats and taller than standard hex nuts, providing greater bearing surface and higher clamp load retention under demanding conditions. This nut carries a right-hand thread with a 2B fit class, making it appropriate for high-strength bolted connections in structural, pressure vessel, and industrial piping applications. It is installed by pipefitters, ironworkers, millwrights, and mechanical contractors who require a fastener that meets ASME B1.1 and ASME B18.2.2 dimensional standards.\u003c\/p\u003e\n\u003cp\u003eThis heavy hex nut is suited for large-diameter bolting applications common in petrochemical, refinery, power generation, and heavy industrial construction. The A194 Grade 2H designation indicates a medium-carbon steel nut heat-treated to achieve a hardness range of 95 HRB to 35 HRC, meeting the mechanical requirements typically paired with ASTM A193 B7 studs and bolts. It is frequently used in flanged pipe joints, pressure vessels, heat exchangers, and structural steel connections where torque retention and dimensional conformance are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA194 Grade 2H steel construction with hardness range of 95 HRB to 35 HRC for high-strength bolting service\u003c\/li\u003e\n  \u003cli\u003eHeavy hex geometry at 3.125 inches across flats and 1.969 inches height provides increased bearing surface versus standard hex\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 2B class thread fit per ASME B1.1 ensures dimensional interchangeability with conforming studs and bolts\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating thickness to account for in precision joint calculations\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.2 fastener dimensional standard\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31161727 for procurement system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 2-8 UN externally threaded fasteners — typically large-diameter studs and bolts manufactured to ASTM A193 Grade B7 or equivalent high-strength specifications used in industrial flanged and structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of large-diameter heavy hex nuts should be performed by qualified tradespeople familiar with torque requirements for the applicable joint standard. Always de-energize, depressurize, and isolate any system before breaking or making bolted connections. Use calibrated torque equipment appropriate for the fastener size and target clamp load; thread lubrication or lack thereof significantly affects required torque values. Follow the applicable piping or structural code — such as ASME B31.3, ASME Section VIII, or AISC specifications — for proper bolt-up sequence and verification.\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: 2-8\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\u003eWidth Across Flats\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.969 inches\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\u003eHardness\u003c\/strong\u003e: 95 HRB - 35 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\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\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: 314700BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701191999794,"sku":"314700BR","price":29.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61a929ffee9418aa8bccbc4fcf0846a0.jpg?v=1788399555","url":"https:\/\/voomisupply.com\/products\/value-collection-314700br-heavy-hex-nut-2-8-a194-2h","provider":"Voomi Supply","version":"1.0","type":"link"}
