How is torque calculated?
Torque is the result of multiplying the value of Force applied by the Distance from the point of application. Comparing the two examples it will be noted that the same resultant Torque can be achieved with a lower Force if the Distance from the nut/bolt is increased. It should also be realised that some torque wrenches are “length dependant” which means that the actual torque applied to the fastener varies if the hand position on the wrench is varied – even with the wrench pre-set! This occurs if the pivot point of the wrench mechanism is not coincidental with the point of application of torque. It should also be realised that some torque wrenches are “length dependant”. This means the actual torque applied to the fastener is dependant on the position of the operator hand on the wrench. This occurs if the pivot point of the wrench mechanism does not coincide with the axis of the fastner. Note: Most Torqueleader wrenches are not length dependant.
