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.

b2ap3_thumbnail_Plane_torque.gifBefore 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.
