Testing and Servicing Torque tools go out of calibration with use. Calibrating a torque tool is a fine tuning process of bringing the tool back within its tolerance. Regular torque calibration of a hand screwdriver ensures accuracy, repeatable tool performance, and adherence to international standards. We recommend a general once a year calibration interval. However, the user's organization must determine suitable intervals based upon equipment performance, application, degree of usage, and management objectives. Mountz Calibration and Repair Services Mountz Inc. features an experienced calibration and repair staff. Our trained technicians can calibrate and repair almost any tool. Mountz provides rapid bration and Repair Services service with quality that you can trust as we offer two state-of-the-art calibration service with quality that you can trust as we offer two state labs and repair facilities that can calibrate up to 20,000 lbf.ft.
