<p>A stop screw with drop-in ball comprises a drop-in ball supporting body which holds the drop-in ball at the top axial end of the body, and support balls for the drop-in ball in the top end. An inner cup like part of deep drawn sheet metal has an open top end at which the drop-in ball is disposed. A hollow screw-housing surrounds the inner part. The inner part has a widened diameter region toward the ball and the axial end of the screw housing engages the widening region of the inner. A radially inwardly directed collar at the top end of the inner part projects inwardly toward the drop-in ball and holds the support balls in the top end. A spring in the inner part presses the ball supporting body through the top of the inner part.</p> |
