How often do torque wrenches require calibration?
The more a wrench is used, the more it will require calibration. Every wrench regardless of use should be calibrated at least every six months to ensure perfect calibration. Production units may require calibration every month, week, or day! Users should be encouraged to maintain wrench calibration and, when establishing their calibration intervals, to request calibration certificates that indicate the readings after the calibration and as the wrench was received.
