P For Angle Control operations, the High and Low Torque limits are either set by the engineering
specification for that specific fastener, or by determining the acceptable limits from a study of known
good and bad assemblies. The High Torque limit will stop the fastening process for Angle Control
operations if it is reached before attaining the desired angle.
