Precision Fine Threaded Ball Ended Adjustment Screws

These precision adjustment screws are designed to be used with our press-in kinematic cones, vee slots and flats. Each has a mating threaded collet available in either plain or locking style. The screws are precision machined from 302/303 stainless steel and provide a smooth and repeatable adjustment. Since the ball end is machined in the same set-up and at the same time that the thread is cut, the ball is concentric to the thread helix to <.0002" TIR. The clearance provided between the ball and the thread allows for insertion into a ninety degree cone or vee slot. Other styles of ball ended adjustment screws with swaged in balls will not allow this stable design.
