Abstract
A system and method for determining the actual torque being applied by an impact tool to a shaft of a fastener is disclosed, wherein an equation having a set of parameters that represent the time-amplitude curve of the individual pulses produced by the impact tool are used to correlate the impact tool pulses and the residual torque in the fastener without requiring knowledge of the torque of the fastener joint.
