6.1.2 Angle Control Method.
In Angle Control method, fastening is performed based upon attaining a desired torque value

NOTE: All setting recommendations are based upon common fastening applications.
Applications that experience high Prevailing torque, excessive joint compression or
other unique characteristics must be set with these characteristics in mind.
NOTE: When performing multiple step Angle control fastening, the rotation Angle
should be performed as one continuous operation. There should be no intermediate
stop/synchronization points once Snug Torque has been sensed and rotation angle is
being controlled. Under special conditions multiple steps can be performed using i
termediate Torque or Angle stop/synchronization points
One-Step Fastening
One-Step fastening will be used primarily for joints that have no requirement to synchronize
with another spindle during the final stage of the rundown.
