Machined from steel and left uncoated, this nut is built for applications where a low-profile locking nut is needed alongside a standard hex or heavy hex fastener. At 1-5\/8 inches across flats and 35\/64 inches in height, it follows heavy hex dimensional standards and is sized for use with 1-inch diameter fasteners. The 2B thread fit class indicates a standard internal thread tolerance suitable for general industrial and structural fastening. Installation is typically performed by millwrights, ironworkers, or maintenance mechanics working on heavy equipment, structural assemblies, or industrial machinery.\u003c\/p\u003e\n\u003cp\u003eThis heavy hex jam nut is used in industrial, structural, and mechanical fastening applications where a jam nut is required to lock a primary nut in place or to provide a low-profile threaded connection on a bolt or threaded rod. The heavy hex profile provides a larger bearing surface and greater wrench engagement than a standard hex nut, making it a preferred choice in high-load or vibration-prone assemblies. It is suited for both shop fabrication and field installation in general industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread specification for use with 1-inch diameter fasteners\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction — standard installation orientation\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile: 1-5\/8 inches across flats for increased wrench engagement and bearing surface\u003c\/li\u003e\n  \u003cli\u003eLow-profile design at 35\/64 inches high — functions as a jam or locking nut\u003c\/li\u003e\n  \u003cli\u003e2B thread fit class — standard internal thread tolerance for general industrial use\u003c\/li\u003e\n  \u003cli\u003eUncoated steel construction — suitable for applications where coating is applied after assembly or not required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy hex jam nut for use with 1-inch diameter, 1-8 UNC threaded bolts, studs, and threaded rod in general industrial and structural fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified mechanics, millwrights, or ironworkers using an appropriately sized heavy hex wrench or socket. Torque the jam nut against the primary nut using a two-wrench method to achieve a proper locking condition. Inspect threads for damage or contamination before installation.
