The U.S. Consumer Product Safety Commission is warning consumers about Richard Abraham Herder torque screwdrivers, long devices used to tighten various metal fasteners.

The organization said the manufacturer initiated a voluntary recall of its "Gedore/Rahsol," Mountz "Titan" and Mountz "Erico" models of which about 670 were sold in the United States.

The screwdrivers' internal spring mechanism can fail causing the screws to break or loosen.

The CPSC said that, so far, it has not received any reports of injuries from the use of this device.

Consumers are urged to contact Klann tools or Mountz Inc., companies that imported the German-made tools, to receive a repaired screwdriver.
