# How to Use a Torque Angle Meter

The calibration of these is in degrees not in pound per square foot though the torque is measure 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.

Instructions

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 damaged.

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.

Tools needed:

• Item to be fastened with nuts and bolts
• Torque wrench
• Torque angle meter
