TORQUE FORCE MEASUREMENT 

Torque screwdrivers and torque wrenches allow the user to adjust the torque to a preset value within a certain range. Torque drivers include a torque-limiting clutch, which disengages once the operator has achieved the preset torque value. Basic torque measurement units include:

• Newton meters (Nm)

• Foot pounds (ft-lb)

• Inch ounces (in-oz)

Newton meters are the most common method of measuring torque. Common torque drivers range from 0.04-27 Nm. No single screwdriver covers the entire range.

Proper and frequent calibration of torque screwdrivers is essential for ensuring uniform assembly values. With these functions and characteristics in mind, consider the following torque-driver testing and calibration and torque measuring tools offered through ROCK.
