An adjustable lock nut comprising a one-piece annular body having an internally threaded axial bore extending between and faces of the body and a circumferential outer face. The body has a narrow annular internal groove that opens intermediate the ends of the axial bore and extends generally radially outwardly from the axial bore. A set of radial bores extend into the body at circumferentially spaced locations with their axes disposed in a plane normal to the body axis and bisecting the internal groove and the radial bores each include an internally threaded outer end portion and a threadless conical inner end portion, configured to form semi-conical recesses in the body at opposite sides of the internal groove adjacent the internally threaded axial bore. An externally threaded screw in the outer end portion of each radial bore actuates a wedge that engages the semi-conical recesses to apply separating forces thereto.
