Greater choice in our series lineup. Compact, lightweight HA25N (* shown connected to optional lightweight battery)

Example of use of HAC series tools

The HACQSPDY/HACQSPDY series is ideal for the Tightening Assurance System, which transmits tightening torque data wirelessly with Bluetooth®.


  • Cell production and assembly work on a sub-line
  • Tightening Data Management System
  • Provides evidence in the form of tightening torque data


  • Far cheaper than an electric hand nutrunner, yet offers high precision torque control.
  • Generally, provisional tightening is done with an electric screwdriver, and then final tightening is done with a torque wrench. But now both provisional and final tightening can be done with a single tool. With “No Wasted Time” there’s no need to switch tools.
  • Provisional tightening is done with a labor-saving brushless electric motor. Final tightening can be done with a torque wrench with ±3% torque control accuracy.
  • Maintenance-free! Uses a durable brushless motor, so there’s no need to ever change brushes.
  • Cordless! Rechargeable battery powers the electric motor for provisional tightening. No power cable for DAC, so no worry about reduced workability or failure caused by a cut cable.
  • Pokayoke (error proofing) is cordless too! Tightened-to-completion signals are transmitted by Bluetooth®, making it easy to build a Pokayoke system to prevent human tightening errors. Cordless operations result in excellent workability, with no worry about cords getting cut.
  • No need for special controller connection. Cordless, so no worries when moving about on the production line, and no need to repair cords.
  • Provisional tightening possible with three-step torque adjustment. With a Bluetooth®-equipped computer, setting software lets you change provisional tightening torque. (* Note: Software available for downloading free of charge.)
  • The software lets you change tightening mode. The setting software can also switch from one mode to the other. Tightening mode 1: For provisional tightening that connects multiple flange bolts. Tightening mode 2: After provisional tightening, if final tightening is missed the next provisional tightening cannot be done. (* Note: Software available for downloading free of charge.)
  • Able to calibrate with a torque wrench tester currently in use. No need for a special calibration device, so traceability at the control level is equal to that achieved with a torque wrench.
  • The compact, lightweight HA25N was launched on the market on January 25, 2016.
  • HAQSPDY/HACQSPDY Series models are capable of sending tightening torque data over wireless connections (Bluetooth(R)), and can be ordered by request only. With the “TDMS/TDMSHT” (Ver. 2.00 or higher) products launched in March 2017, users can construct tightening data management systems.
  • Except for some products, the HA/HAC/HACQSPDY series are compliant with ISO 6789:2017 starting January 2022. For more information, see the technical data “Initiatives for ISO 6789:2017” at the bottom of the screen.
  • Can use wireless Bluetooth® technology to manage HACQSPDY tightening data. * Use Excel® on your computer to manage data received via the free DtRcv (Data Receiver) software. DtRcv is included in software under the screen. (Setting software included.)
