ABSTRACT:
A workpiece holding system with lock screw in which the lock screw is placed axially in the center of an adjustment screw for an adjustment block thereby eliminating any deflection and eliminating any small errors. Since the lock screw is already spring pressured on the adjustment screw, the increased pressure of the lock screw will not cause any change in the adjustment of the adjustment block and since the lock screw is oriented in the center of the adjustment screw, there will be no deflection of the adjustment block.
