Manufactured from steel with an uncoated finish, this nut carries a 2B class of fit, making it appropriate for standard fastening applications that call for a heavy hex profile. At 4-1\/4 inches across the flats and 2-45\/64 inches in height, it is significantly larger and heavier than a standard hex nut, providing greater bearing surface and load distribution. Weighing 7.38 pounds, it is suited for structural and heavy industrial assemblies where standard hardware is insufficient.\u003c\/p\u003e\n\u003cp\u003eThis heavy hex nut is used in structural steel construction, heavy equipment assembly, pipeline flanges, industrial machinery, and other applications requiring large-diameter fasteners with a UNC thread form. The 2B class of fit indicates a standard internal thread tolerance suitable for general industrial use. Installations are typically performed by millwrights, ironworkers, pipefitters, or maintenance mechanics working on large-scale mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-3\/4 - 4 UNC thread specification for large-diameter fastening applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction — standard installation with clockwise tightening\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile at 4-1\/4 inches across flats provides increased bearing surface\u003c\/li\u003e\n  \u003cli\u003e2B class of fit for standard industrial thread tolerance\u003c\/li\u003e\n  \u003cli\u003eUncoated steel construction for use where additional coatings are not required\u003c\/li\u003e\n  \u003cli\u003e7.38-pound weight reflects the robust cross-section of the heavy hex form\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 2-3\/4 - 4 UNC threaded fasteners in heavy hex nut applications.

Always de-energize and lockout equipment before performing fastener service on mechanical or electrical assemblies. Structural bolting applications may fall under AISC, RCSC, or applicable local building code requirements — verify the applicable specification before installation. Do not mix thread standards or grades within a fastener assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-3\/4 - 4 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 Standard\u003c\/strong\u003e: UNC\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\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcross Flats\u003c\/strong\u003e: 4-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2-45\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.38 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: 309738MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723266654514,"sku":"309738MSC","price":137.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52f9cdb264bc9c5a57eb75ce1aed8ccc.jpg?v=1788602422","url":"https:\/\/voomisupply.com\/products\/value-collection-309738msc-heavy-hex-nut-2-3-4-4-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
