A locking nut is disclosed for locking engagement with an element such as a bolt, rod, stud or the like, the element having a cylindrical screw-threaded outer surface. The locking nut includes a main nut having a thread for engaging the cylindrical screw-threaded outer surface of the element. A cylindrical sleeve integrally contiguous to a first end of the main nut extends longitudinally therefrom. The sleeve has a cylindrically threaded interior surface for engagement with the outer surface of the element to permit longitudinal motion of the sleeve along the outer surface of the element. The cylindrical sleeve also has a cylindrically screw-threaded exterior surface, coaxial with the cylindrical sleeve interior surface, the threading on the sleeve exterior surface having a greater flank angle than the threading on the sleeve interior surface. A secondary nut threadedly engages the sleeve exterior surface, the secondary nut having a first end confronting the first end of the main nut. The secondary nut is carried by the cylindrical sleeve and is longitudinally movable with respect to the sleeve into an abutting relation with the main nut first end. Further rotation of the secondary nut subsequent to the initial abutting relation causes a force to be transmitted through radial compression of the cylindrical sleeve to the element outer surface for securing the cylindrical sleeve against longitudinal motion along the element outer surface with a user determined clamping force.
