•Automatic torque converter enables stable bolt tightening high speed for provisional tightening and low speed for final precise tightening.

•Fluctuation of the air pressure does not affect the accuracy and repeatability.

•Easy torque adjustment with graduation.

•Unlock device releases all reaction forces which prevents the removal of the tool after the bolt has been driven to the desired torque.

•Reaction force is automatically and safely absorbed in any position with a universal reaction arm.

•Since the reaction arm rotates free, the positioning can easily be made by moving the reaction arm.
