How to Use a Torque Meter
Torque meter which are also called torque gauges are instruments used to ensure a
fastener is tightened at the right strength and with equal tightness where necessary.
The calibration of these is in degrees not in pounds per square foot though the torque is
measured with the latter unit. This is to avoid errors that could be brought about by the
friction of threads of screws. Learning how to use an angle meter is easy and the
following is an easy guide to it.
• Item to be fastened with nuts and bolts
• Torque wrench
• Torque meter
1. Get the specifications of the strength of fastening for the faster that you have got for
tightening to learn the correct value for the torque for the particular fastener. These
values are normally given on pound per square foot. Check if the angle value in degrees
is also given. If you use the incorrect values the item you are going to fasten will get
2. Take the two pieces to be fastened and fasten them. Then tighten the fastener using
a standard torque wrench to the torque given in the specification. Now fix the torque
angle meter on the head of the fastener. Now put the standard torque wrench on the
torque angle meter.
3. Now tighten by turning the standard torque wrench using the specifications to reach
the figure given in it. The meter will indicate the strength in degrees. You need to watch
the angle meter very carefully to get the correct value on it. You can finish the job when
the required Torque meter is obtained. In case you have more fasteners in the same
application make sure that you tighten all of them to the same degree or at least as
close as possible.
