Differences between types:

Click type torque wrenches are 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 malfunction. Beam type torque wrenches are impossible to use in situations where the scale cannot be directly 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 (On some older designs). There is also the issue of increased user error with the beam type—the torque has to be read at every use and the operator must use caution to apply loads only at the floating handle's pivot point.

However, for inherent accuracy, the beam (P.A. Sturtevant / Chrysler Engineering) type wins hands-down[citation needed]: As long as the pointer is free to move, and rests at zero (or is bent to achieve this), 100% accuracy is inherent -- no matter how shoddy, rusty, dinged, etc., the tool may appear. Dual-beam or "flat" beam versions reduce the tendency for the pointer to rub, as do low-friction pointers.

For the click type, when not in use, the force acting on the spring should be removed by setting the scale to 20% of full scale in order to maintain the spring's strength. Never set a micrometer style torque wrench to zero as the internal mechanism requires a small amount of tension in order to prevent tool failure due to unwarranted tip block rotation.

If a micrometer tool has been stored with the setting above 20% the tool should be set to 50% of full scale and exercised at least 5 times before being used. In the case of the beam type, there is no strain on the component that provides the reference force except when it is in use, therefore, accuracy is inherent.
