Calibrating Torque Screwdrivers To calibrate a torque screwdriver, either use a torque analyzer or torque sensor within the range of the torque screwdriver. For a torque screwdriver calibrate torque in "Peak" mode with a torque tester or torque sensor. Make sure to apply the torque slowly and smoothly. 1. Select a torque tester or torque sensor that covers the torque range of the screwdriver. Connect the screwdriver to the
torque tester or torque sensor using the appropriate adapters as needed. 2. Apply torque clockwise slowly until screwdriver 'slips' and note reading. 3. Adjust screwdriver to required torque setting as described above. 4. Test and repeat adjustment as necessary to obtain the desired torque value. 5. Recalibrate torque screwdriver at prescribed intervals.
Maintenance Schedule Like an automobile, torque screwdrivers contain moving parts that require periodic servicing and lubrication.
Expected Tool Life With normal use – 1,000,000 operations
Period Between Resetting of Torque 20,000 fastening operations. It is acknowledged that some tools may achieve 20,000 operations in a relatively short period of time. Under these circumstances, the user may decide, with the benefit of their experience, to increase the period between calibration intervals. Routine Maintenance After 100,000 operations, strip, clean, and re-grease the spring, bearings, and internal components. Any worn components should be replaced. Note: Any tool that is dismantled during its life must be re-lubricated in accordance with the Mountz recommendations. Do not clean tools by immersing them in a solvent, as this will destroy the internal lubrication and cause the tool's failure.
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.
