NOTE: When performing multiple step Angle control fastening, the rotation Angle should be
performed as one continuous operation. There should be no intermediate stop / synchroniza-
tion points once Snug Torque has been sensed and rotation angle is being controlled.
Under special conditions multiple steps can be performed using intermediate Torque or Angle
stop/synchronization points as shown below.
