The Jam Nut 1/2-20 Steel RH from FK Rod Ends is a precision fastening component designed for high-performance rod end assemblies and threaded suspension components. This jam nut is essential for mechanics and fabricators who need to secure rod end sphericals and threaded studs in place, preventing loosening during engine vibration and suspension articulation.
Manufactured from hardened steel, the Jam Nut features a right-hand (RH) thread profile with a 1/2-inch diameter and a standard 20 threads-per-inch pitch. Its compact design (0.3 inches wide) allows for tight installation against rod end bearings, while the steel construction resists galling and thread stripping, common in aluminum-bodied assemblies. The jam nut utilizes a friction lock mechanism, which, when torqued against a primary nut, creates resistance against vibration-induced loosening.
Ideal for chassis builders, drag racing teams, drifters, and off-road suspension engineers, this jam nut provides reliability under shock loads and continuous flex. It pairs seamlessly with FK Rod Ends' full line of spherical bearings, making it a versatile choice for various automotive applications.
