It carries a 5\/8-11 UNC thread designation with a right-hand thread direction and a 2B thread fit class per ASME B1.1 and ASME B18.2.2. Hardness is rated at 24-35 HRC, making this nut suitable for high-strength bolting applications where torque retention and structural integrity are critical. It measures 1.0625 inches across the flats and 39\/64 inch in height. Maintenance technicians, pipefitters, millwrights, and structural tradespeople specify this grade for demanding service conditions.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is used in heavy industrial, structural, and pressure-flange bolting applications where A194 Grade 2H specifications are required. Common install scenarios include pipe flange assemblies, structural steel connections, pressure vessel service, and general mechanical fastening in environments with elevated load or vibration. The uncoated finish suits indoor or protected environments or applications where a specific coating will be field-applied after assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA194 Grade 2H steel construction rated at 24-35 HRC hardness for high-strength bolting service\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC right-hand thread, 2B fit class per ASME B1.1\u003c\/li\u003e\n  \u003cli\u003eDimensions conform to ASME B18.2.2 heavy hex nut standards\u003c\/li\u003e\n  \u003cli\u003e1.0625 inches across the flats, 39\/64 inch height for standard wrench compatibility\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for field coating or protected-environment use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or new-installation hex nut for 5\/8-11 UNC threaded fastener systems conforming to ASME B18.2.2 and A194 Grade 2H material requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, pipefitters, or structural ironworkers using calibrated torque wrenches appropriate for the fastener grade and joint specification. Power down or depressurize any system before servicing fasteners on live mechanical or pressure assemblies. Follow applicable code requirements, including ASME standards for pressure-boundary bolting, and verify thread engagement and nut seating before applying final torque. Do not mix A194 Grade 2H nuts with incompatible bolt grades without confirming joint design requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\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: 1.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 39\/64 inch\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\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: 36657\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689044967730,"sku":"36657","price":2236.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4bd6c4f239f4ed77a9d5f09cce269f4.jpg?v=1788254194","url":"https:\/\/voomisupply.com\/products\/value-collection-36657-hex-nut-5-8-11-a194-grade-2h","provider":"Voomi Supply","version":"1.0","type":"link"}
