Made from A194 Grade 2H steel with a bright, uncoated finish, this nut meets ASME B1.1 and ASME B18.2.2 standards. The 1-3\/4-8 thread size and 2B fit class provide reliable engagement on heavy-duty fastener systems. Hardness is rated between 95 HRB and 35 HRC, making it suitable for high-load and high-temperature service conditions. Maintenance crews, pipefitters, millwrights, and structural ironworkers commonly install this type of heavy hex nut during equipment assembly, flange connections, and structural bolting work.\u003c\/p\u003e\n\u003cp\u003eThis heavy hex nut is used in industrial piping, pressure vessel fabrication, structural steel connections, and heavy mechanical assemblies. The A194 Grade 2H designation makes it a common choice for bolted flange joints and heat exchanger connections where elevated temperature and pressure performance are required. The uncoated finish suits applications where a subsequent coating or galvanizing will be applied in the field, or where bare steel is acceptable per engineering specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA194 Grade 2H steel construction rated for high-strength, high-temperature service\u003c\/li\u003e\n  \u003cli\u003e1-3\/4-8 right-hand thread with 2B fit class for standard heavy hex fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 inch width across flats for use with standard heavy hex tooling\u003c\/li\u003e\n  \u003cli\u003eHeight of 1-23\/32 inches provides full thread engagement depth\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B1.1 and ASME B18.2.2 dimensional and thread standards\u003c\/li\u003e\n  \u003cli\u003eHardness range of 95 HRB to 35 HRC suitable for demanding load conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style heavy hex nut for use with 1-3\/4-8 UN-threaded fasteners in structural and industrial bolted joint applications conforming to ASME B18.2.2.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by pipefitters, millwrights, or structural ironworkers using calibrated torque wrenches or hydraulic tensioning equipment sized for 1-3\/4-inch fasteners. De-energize, depressurize, and lock out the system before servicing any bolted joint. Follow applicable ASME, OSHA, or engineering torque specifications provided in the project documentation — do not estimate torque for heavy structural or pressure-retaining joints. Inspect thread condition on both nut and bolt before assembly to ensure proper fit class 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\/4-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-23\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 95 HRB - 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: 0.03 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: 314600BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721225568562,"sku":"314600BR","price":48.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a279d45f87ade18aa33d4621fbd712b.jpg?v=1788575081","url":"https:\/\/voomisupply.com\/products\/value-collection-314600br-heavy-hex-nut-1-3-4-8-a194-2h","provider":"Voomi Supply","version":"1.0","type":"link"}
