It is designed for 2-4-1\/2 UNC (Unified National Coarse) thread applications with a 2B thread fit class and right-hand thread direction. This nut measures 3.125 inches across the flats and 1.969 inches in height. It conforms to ASME B1.1 and ASME B18.2.2 fastener standards. Licensed trades and industrial maintenance professionals use this hardware in heavy-duty structural, pressure vessel, and piping bolted connections where high-strength fastener assemblies are required.\u003c\/p\u003e\n\u003cp\u003eThis heavy hex nut is suited for use in industrial, commercial, and infrastructure applications that demand high-load fastener performance. The A194 Grade 2H designation indicates a carbon or alloy steel heavy hex nut intended for use with high-strength bolts in pressure piping, structural steel, and flanged joint assemblies. The wider hex profile compared to a standard hex nut provides greater bearing surface and wrench engagement, making it appropriate for critical bolted connections in mechanical and process piping systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA194 Grade 2H steel construction rated for high-strength bolting applications\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile with 3.125 inches across flats for increased bearing surface and torque capacity\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread, 2-4-1\/2 UNC thread size with 2B fit class per ASME B1.1\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use as-received or for subsequent coating\u003c\/li\u003e\n  \u003cli\u003eHardness range of 95 HRB to 35 HRC for consistent clamp load performance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.2 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy hex nut for use with 2-4-1\/2 UNC threaded fasteners in structural, pressure vessel, and industrial piping bolted assemblies conforming to ASME B18.2.2 requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, pipefitter, or structural iron worker following applicable codes such as ASME, AISC, or ANSI piping standards.
