Manufactured from A194 Grade 2H steel with a bright uncoated finish, this nut meets the requirements of ASME B18.2.2 and ASME B1.1. It features a 1-1\/8-8 UN thread size with a right-hand thread direction and a 2B thread fit class. Hardness is rated at 24-35 HRC, making it well suited for high-load fastener applications. Plumbers, pipefitters, structural ironworkers, and mechanical contractors commonly specify A194 Grade 2H nuts for pressure flange connections and structural bolting.\u003c\/p\u003e\u003cp\u003eThis hex nut is used in heavy industrial and commercial settings where high-strength fasteners are required. Typical applications include pressure vessel flange bolting, pipe flange assemblies, structural steel connections, and heavy equipment mounting. The A194 Grade 2H designation is commonly paired with A193 Grade B7 threaded rod or stud bolts in pressure and temperature-rated piping systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA194 Grade 2H alloy steel construction rated at 24-35 HRC hardness\u003c\/li\u003e\n\u003cli\u003e1-1\/8-8 UN right-hand thread, 2B fit class per ASME B1.1\u003c\/li\u003e\n\u003cli\u003eWidth across flats: 1-13\/16 inches (1.8125 inches)\u003c\/li\u003e\n\u003cli\u003eHeight: 1-7\/64 inches\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for further coating or use as-is\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.2 heavy hex nut dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-1\/8-8 UN threaded fasteners in high-strength bolted assemblies conforming to ASME B18.2.2 and ASME B1.1 standards.

De-energize and depressurize the system completely before working on any flanged connection. Fastener torque should be applied in accordance with applicable engineering specifications and governing codes such as ASME PCC-1 for pressure flanges or applicable structural codes. Do not reuse nuts that show signs of thread damage, galling, or deformation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-8\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: 1-13\/16 inches (1.8125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-7\/64 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\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: MSC-67481762\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717627117874,"sku":"MSC-67481762","price":45.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab8f9b4433ae000c45504a2445bead40.jpg?v=1788543674","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-67481762-hex-nut-1-1-8-8-a194-2h","provider":"Voomi Supply","version":"1.0","type":"link"}
