How do I use a torque wrench?

Click type torque wrenches are more precise when properly calibrated—however the more complex mechanism can result in them losing calibration far quicker than the beam type, where there is little to no malfunction. Beam type torque wrenches are impossible to use in situations where the scale cannot be read—and these situations are common in automotive applications. The scale on a beam type wrench is prone to parallax error, as a result of the large distance between indicator arm and scale. There is also the issue of increased user error with the beam type—the torque has to be read off each and every use.
