The right solution for everyone

Leiter Arbeitsvorbereitung

Andreas, Head of Work Planning

The perfect solution for digitalising our production line.

We were looking for a functional and flexible solution for digitalising a small production line. Many solutions were too complex for this purpose and required a high investment. We found the perfect solution in the HCT Windows app. I can now easily create and customise workflows myself. The settings are reliably transferred onto the tool and can be used by the operator.


Marco, Assembler

Thanks to HCT, I work more efficiently and with fewer errors than before.

All the settings are pre-programmed into the tool and the software guides me through the assembly steps. This means I don't forget any of the steps and I finish faster. In addition to this, I no longer have to manually document the measurement values and therefore have more time for my measurement tasks.


Verena, Quality Assurance

The automated documentation system records our measured data reliably and in a traceable way.

Manual data transfers often resulted in errors and meant expensive reworking. Now, the measurement data is recorded directly from the tool in a complete, secure and verifiable way. Data tampering is prevented, which enables us to supply our customers with traceable, high-quality products.

Modern features to optimise your production process

  • Worker guidance – visually supported with images for each screwdriving case
  • Password protection to prevent unauthorised access
  • CAQ connection (MUX50, DMX16 protocols)
  • .csv or .dfq files stored in a local folder
  • The workpiece’s serial number is linked directly and automatically to the associated measurement value Up to 16
  • HCT tools can be connected to a PC/laptop at the same time for each dongle
  • Processes can be planned via the app (thanks to the bidirectional interface, screwdriving cases do not need to be created on the tool)


  • Which firmware version does my tool need to use the HCT Windows app?

    GARANT electronic torque wrench 655010: Firmware Version: 3.31; BLE Version: 0.89

    HOLEX Electronic torque wrench 655025: Firmware Version: 1.1.5; BLE Version: 1.2.22

    Here you will find the latest firmware versions for your HCT tools.

  • Which version of Windows is required?

    Windows 10 or later

  • How far can the computer and the measuring device be from one another?

    In industrial environments: approx. 15 m

  • How do I connect the HCT Windows app to my CAQ software?

    The HCT Windows app allows data to be transferred to CAQ systems via COM ports. We recommend the use of virtual COM ports as provided by the Null-modem emulator from com0com (the link to this can be found further up with the downloads). The measurement values can be sent using the MUX50 or DMX16 protocol. If it is not possible to install suitable null-modem software, a hardware null modem can be used. If this is the case, please contact our support team, who can offer you a suitable device.

  • How do I uninstall the HCT WIN software?

    As per the standard Windows uninstall process
