New: Torque Wrench Calibration Machine

About AWS

The all new AWS Torque Wrench Calibration Machine (TWCM) provides an efficient means of calibrating and testing manually operated torque wrenches to international or company specific standards and specifications.

The TWCM is available in two versions; both apply the force to the tool via a linear carriage stepper motor and an AWS microcontroller.  

An important feature is the minimization of parasitic forces applied to the torque wrench handle.

Both machines can be used with our new AWS/ ADMS Kepler 4 software to speed up completion of the calibration & certification process to ISO 6789:2017, ISO 6789:2003 or type approval for manufacturers.

Need help with ISO 6789:2017?


ISO 6789 is the internationally recognised standard to which torque wrenches must be calibrated.

A calibration certificate to ISO 6789 states that a tool meets quality control regulations and accurately applies the correct torque.

AWS have produced a white paper highlighting the main changes and requirements. It can be viewed by clicking below:
