Sized at 1-1\/4-7 UNC with a right-hand thread and a 2B fit class, this nut meets ASME B1.1 and ASME B18.2.2 dimensional standards. The uncoated bright finish leaves the steel surface bare for applications where galvanic compatibility or post-installation coating is required. Hardness is Rockwell C24-35, giving it the mechanical strength required for pressure vessel flanges, structural connections, and heavy equipment fastening. Installers in industrial maintenance, pipefitting, and structural steel trades specify A194 Grade 2H nuts for pairing with high-strength bolting.\u003c\/p\u003e\u003cp\u003eThis hex nut is used in heavy industrial settings where bolted flange joints, pipe hangers, structural steel connections, and pressure-rated assemblies require a nut that meets published ASME fastener standards. The 1-1\/4-7 UNC thread size is common in large-diameter pipe flange bolting and structural steel work. Typical installers include pipefitters, millwrights, ironworkers, and industrial maintenance mechanics working on process piping, pressure equipment, and steel structure assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA194 Grade 2H steel construction meets ASME B18.2.2 heavy hex nut dimensional standards\u003c\/li\u003e\n\u003cli\u003e1-1\/4-7 UNC right-hand thread with 2B fit class for standard bolt engagement\u003c\/li\u003e\n\u003cli\u003eRockwell C24-35 hardness rating suitable for high-load and pressure-rated joints\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with post-installation coating or galvanic isolation requirements\u003c\/li\u003e\n\u003cli\u003e2 inch width across flats; 1-7\/32 inch height for standard wrench and socket fit\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B1.1 and ASME B18.2.2 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service nut for 1-1\/4-7 UNC heavy hex bolting applications conforming to ASME B18.2.2 standards.

De-energize or depressurize any system before replacing fasteners on live flanges or structural joints. Use calibrated torque wrenches and follow the applicable flange bolt-up sequence to achieve uniform gasket load. Do not mix nut grades or coatings within a single bolted joint unless the applicable engineering specification permits it.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7 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\u003eThread Standard\u003c\/strong\u003e: ASME B1.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.2.2\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: Rockwell C24-35\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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-7\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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-67481804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694162116914,"sku":"MSC-67481804","price":23.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6efac4c7dd97c32674229fd59e0948ba.jpg?v=1788321099","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-67481804-hex-nut-1-1-4-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
