Adjustment & Calibration

Torque wrenches are used for connections with a precisely pre-defined torque. The accuracy of the wrenches and the correctness of the set values is therefore essential.

We strictly recommend an annual inspection and calibration of your torque wrenches. Please note that the inspection interval can be reduced if you reach the recommended upper limit of 5,000 load cycles earlier through more intensive use. For adjustment/calibration, please send your HAZET torque wrench to our service centre. You can ship it to us directly or via your specialist dealer. Alternatively, we also offer the maintenance service box:


If you want a DAkkS calibration, please contact our accredited calibration laboratory.
