Torque Wrenches

Calwest Services offer repairs and servicing of your torque wrenches and torque transducers to ensure reliable operation. We will clean and lubricate the instrument as part of our calibration service. We offer part replacements for Norbar and Moore & Wright torque wrenches, and can repair any brand of torque transducer.

If your torque wrench is worn or damaged beyond repair, Calwest Services can supply a replacement torque wrench with a calibration certificate for wrenches up to 1500Nm.

To ensure accuracy and instrument reliability, Calwest Services recommends the following preventive maintenance and usage guide:

Usage Guide
  • Always follow the manufacturers recommendations. Follow the correct torque sequence, torque settings, and fastener lubrication recommendations.
  • If your torque wrench is a spring based device, ensure the torque wrench is stored with the spring unwound – ie minimal torque setting.
  • Use other means to tighten and loosen fasteners, and only use the torque wrench to set the torque value.
  • Smoothly apply force in a slow, deliberate manner and avoid jerking.
  • Do not use a handle extension. Torque wrenches are length specific and should only be grasped in the centre of the handle grip.
  • Immediately stop applying force once the torque wrench clicks. This indicates that the desired torque has been reached.
Preventive Maintenance
  • Regularly inspect and lubricate the torque wrench, and replace any missing or worn parts.
  • Do not drop the instrument, this can lead to damage and lose of calibration.
  • Store the torque wrench in a dry and humid-free place, preferably in its original protective case, and set the scale to its lowest setting.
  • Be mindful of the work environment. Avoid extreme temperatures, moisture, and excessive dust.
  • Always clean the torque wrench after use.It is recommended to have your torque wrench calibrated and serviced annually, depending on use.
