How To Use Your New Torque Wrench
Torque is twist or the resistance to rotation.When used in reference to a bolt. torque is the resistance to turning of the bolt or nut.
Tension is straight pull and is measured in pounds.
Torque wrenches are at times referred to as tension wrenches. This is not true.
Wrenches that are designed to measure or limit the amount of torque applied to a nut or bolt are definitely torque measuring instruments.
A torque wrench is precision measuring instrument much the same as a micrometer, dernier calipers or any other accurate measuring instrument. Its purpose is to measure of limit the amount of torque being applied at a given point.
What Does Torque Do to a Bolt?
Applying the exact amount of torque to a nut or bolt induces the correct amount of tension or elongation in the bolt that is necessary to hold the parts together. Furthermore, by applying the correct amount of torque specified to a bolt the danger of distortion to the part or adjoining parts is eliminated.
IMPORTANCE OF ACCURATE TORQUE
If a nut or bolt is not tightened enough it will eventually work loose and drop off. At the other extreme if too much torque is
applied the nut or bolt will very likely snap off. In either event an obvious failure occurs due to improper torquing of the fastener.
Torque is based on the fundamental law of the lever-that is -force times distance equals the torque or twist around a point.
Torque is most commonly measured in foot pounds or inch pounds. For example : if a 1 pound force is applied 1 foot from the center of the bolt the resulting torque developed would be referred to as one foot pound of torque.
If a 1 NEWTON force is applied 1 METER from the center of the bolt the resulting torque developed would be referred to as one NEWTON- METER of torque.
