Manufactured from A194 Grade 2H steel with a bright, uncoated finish, this nut meets the dimensional and mechanical requirements of ASME B18.2.2 and the thread standard ASME B1.1. The 1-1\/2-8 UN thread size with a 2B fit class provides reliable engagement on heavy-duty fastener assemblies. Hardness is rated at 24 to 35 HRC, making it appropriate for high-load and high-temperature service environments. Installers, millwrights, pipefitters, and structural ironworkers commonly use this nut when assembling flanged joints, structural steel connections, and pressure-rated equipment.\u003c\/p\u003e\u003cp\u003eThis heavy hex nut is suited for use in industrial construction, pressure vessel fabrication, structural steel erection, and process piping work. The 1-1\/2-8 thread size is common in large-diameter flange bolt assemblies and anchor bolt applications. The A194 Grade 2H designation is widely specified in ASME and ASTM-referenced fastener standards for bolting materials used in pressure and temperature service. This nut ships individually and is available in single-unit quantities, making it practical for replacement or low-volume maintenance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA194 Grade 2H steel construction for high-strength bolted joint service\u003c\/li\u003e\n\u003cli\u003eHardness range of 24 to 35 HRC for consistent mechanical performance\u003c\/li\u003e\n\u003cli\u003eRight-hand, UN thread form per ASME B1.1 with 2B fit class tolerance\u003c\/li\u003e\n\u003cli\u003eHeavy hex profile per ASME B18.2.2 for increased wrench bearing surface\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no additional coating or plating applied\u003c\/li\u003e\n\u003cli\u003eWidth across flats of 2-3\/8 inches for standard heavy hex tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy hex nut replacement or new-installation fastener for 1-1\/2-8 UN threaded bolt assemblies requiring A194 Grade 2H material compliance per ASME B18.2.2.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by pipefitters, millwrights, or structural ironworkers using heavy hex wrenches or hydraulic torquing equipment sized for 2-3\/8-inch across-flats geometry. Always verify thread engagement and cleanliness before assembly. Follow applicable code requirements, such as ASME PCC-1 for pressure boundary bolted flange joint assembly, for proper torque sequencing and lubrication practices. Do not mix with nuts of different grade or thread class in a shared bolt assembly.\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: 1-1\/2-8\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\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-15\/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: 314500BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689505030450,"sku":"314500BR","price":27.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e68238022e0ffa55b607c420fc285a0.jpg?v=1788260567","url":"https:\/\/voomisupply.com\/products\/value-collection-314500br-heavy-hex-nut-1-1-2-8-a194-2h","provider":"Voomi Supply","version":"1.0","type":"link"}
