To ensure that bolts and nuts are tightened with the correct torque, it makes sense to calibrate the torque wrenches regularly.
Calibration and adjustment of torque wrenches are performed in accordance with ISO 6789-1 & 2. All our calibrations are performed with the best references and the certificate contains uncertainty calculations.
To ensure our quality, we participate in comparison tests with other providers of the same services and we can point to full traceability of our references.
