The Giustaforza 1-8 is especially attractive for very sensitive bolts. On those, where the right torque matters most, tightening values can be easily exceeded without the user knowing. Going as low as 1 Nm puts the Giustaforza 1-8 in a league on its own. In use, always refer to the torque values specified on technical documents or printed on the parts themselves.
The +-4% tolerance is guaranteed for 5000 cycles (5000 ‘clicks’), then the wrench should be re-calibrated. Calibration is offered in Lugano Switzerland
With every calibration, the tolerance of +-4% over nominal value will extend for 5000 cycles. After calibration, the wrench will return to the customer with a calibration certificate.
