Norwolf Calibore Calibration Services

Calibration is necessary for Norwolf Calibore Bolt Tension Calibrators at least once a year to ensure that they are operating accurately and reliably. We make the process quick and seamless by offering in-house calibration services performed by a veteran team of expert technicians. Your tools will be skillfully calibrated and returned to you in record time, so you can get back to work as soon as possible.

Norwolf Calibore Bolt Tension Calibrators are used to verify that bolts meet the minimum bolt tension specifications; that TC Bolts shear off at the proper tension; and that Direct Tension Indicating (DTI) washers are indicating proper tension. Calibore calibrators can be used with impact wrenches, manual, pneumatic and hydraulic torque wrenches, nut runners, hydraulic bolt tensioners, torque multipliers and TC shear bolts.
