A torque wrench is one of those tools found everywhere from aerospace settings to home mechanics and bicyclists’ toolboxes. Its ability to tighten fasteners accurately to a particular force makes it indispensible. Torque wrenches (and other torque tools including torque transducers) must be calibrated to work properly.
Before using your torque wrench, make sure it has been calibrated and that its calibration date has not expired. New torque wrenches may arrive with a matching certificate of calibration traceable to NIST.
Test your torque wrench monthly for accuracy. At least once a year, your wrench should be recalibrated. In some settings, you must test for accuracy more often—perhaps before each use. Of course, as a tool, the torque wrench may be dropped or mishandled somehow. If this is the case, make sure you get it recalibrated.
InnoCal’s environmentally-controlled lab has been evaluated by A2LA and confirmed for technical competency for torque and force calibrations. We also have a fleet of mobile standards to perform calibrations on site at your facility.
