A screw stabilizer for selectively adjusting a first element with respect to a second element. The screw stabilizer includes a screw having a first end adapted to be supported on the first element and a second threaded end to be adapted to be threaded to the second element. First and second opposing washers are supported on the first end of the screw. The first washer includes a plurality of radially extending detents on the inner surface thereof. A plurality of ball bearings are sandwiched intermediate the first and second washers. The first end of the screw presses the first and second washers towards one another. The ball bearings selectively ride in the detents to selectively, releasably lock the screw in a desired position.
