A ball nut having a ball return tube is formed with an externally threaded stud for supporting a mounting flange which is adapted to be screwed onto the stud. Angularly spaced segments of resiliently compressible wire are seated in an annular groove in one face of the flange. When the flange is screwed onto the stud, the segments engage a shoulder on the nut and compress to enable the flange to be tightened to a position in which the flange is in a predetermined angular orientation relative to the ball return tube.
