Jam nuts are thinner than standard full hex nuts, making them the correct choice for lock-nut applications where two nuts are threaded against each other to prevent loosening under vibration or dynamic load. The right-hand thread engages standard 1\/2-13 UNC fastener systems. At 5\/16 inch in height and 3\/4 inch across the flats, this nut fits a standard 3\/4-inch wrench or socket. Grade 2 carbon steel suits general-purpose mechanical and structural fastening work across trade and industrial settings.\u003c\/p\u003e\u003cp\u003eThis jam nut is used in general mechanical assembly, HVAC equipment mounting, plumbing fixture support, electrical enclosure hardware, and similar trade applications where a low-profile locking nut is required on a 1\/2-13 UNC threaded rod, bolt, or stud. The uncoated finish is appropriate for dry or protected indoor environments. Installers working in corrosive or exterior environments should evaluate whether a coated or stainless alternative is required for the application.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eJam-nut profile at 5\/16 inch height for low-profile lock-nut applications\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC right-hand thread for compatibility with standard inch-series fasteners\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction for general-purpose mechanical fastening\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish with 3\/4 inch across-flats dimension fitting standard tooling\u003c\/li\u003e\n\u003cli\u003eSold individually; minimum order quantity is 50 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2-13 UNC threaded fasteners including bolts, rods, and studs following Unified National Coarse thread specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/4-inch wrench or socket. When used as a jam nut, thread it against a primary nut and torque both nuts against each other to secure the assembly.
