Tohnichi has developed HAC wrench series (5 models) and launched sale on March 2.

It is common that an operator has to temporarily  fasten with an electric driver and then finalize fastening with a torque wrench. HAC wrench totally removes the need for temporary fastening, and a single HAC wrench can complete the whole fastening process without changing tools. HAC wrench has a bluetooth transmitter to send a "done fastening" signal when the wrench confirms that no fastener is left unfastened. An "R-BT" bluetooth signal receiver (selling separately) and a "CNA-4mk3" counting device connected to the wrench via a cable make a simple error-proofing mechanism to prevent unfastened fasteners. HAC is a battery-type wrench so there is no need to connect it with a power cable. It has excellent operability and there is no need to worry about broken power cable.
