Stahlwille electromechanical torque screwdriver with 1/4" internal hex drive
The first electromechanical torque screwdriver on the market - combines the accuracy of electronic measurement with the convenience of the "click" from mechanical trigger mechanisms.

The rechargeable batteries can be quickly and easily changed.
