P For Torque Control operations, the High and Low Angle 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 Angle limit will stop the fastening process for Torque Control
operations if it is reached before attaining the desired torque.
