It carries a Rockwell C24-35 hardness rating, making it well suited for high-strength bolted assemblies where consistent clamp load and resistance to loosening under load are required. The 2B thread fit class ensures proper engagement with standard UNC external threads. This nut is installed by millwrights, structural ironworkers, pipefitters, and industrial maintenance mechanics in bolted connections on pressure equipment, structural steel, and heavy machinery.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is appropriate for use in industrial, structural, and pressure vessel applications where ASME B18.2.2 heavy hex geometry and A194 Grade 2H material are specified by design or code. The right-hand thread direction conforms to ASME B1.1 UNC standards. It is commonly used in flange bolting, structural connections, and other assemblies demanding certified high-strength fastener hardware. Always verify that the mating bolt or stud meets the corresponding strength and thread specification before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA194 Grade 2H steel construction with Rockwell C24-35 hardness for high-strength bolted connections\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC right-hand thread, 2B fit class for standard mating with UNC external threads\u003c\/li\u003e\n  \u003cli\u003e1-7\/16 inches across flats for use with standard hex drive tooling\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for applications where coating is not required or will be field-applied\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B1.1 and ASME B18.2.2 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 7\/8-9 UNC threaded bolts and studs in structural, pressure vessel, and industrial mechanical assemblies requiring A194 Grade 2H certified hex nuts per ASME B18.2.2.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with ASME or applicable structural bolting codes. De-energize or depressurize the assembly before servicing any fastener in a live system.
