Torque to angle means:

Torque to angle combines two steps to control preload. First you tighten the fastener to the seating torque to bring the parts into full contact and establish initial clamping. Then you apply a specified amount of angular turn (an exact rotation) to stretch the bolt a precise amount, which sets the final clamp load more consistently than torque alone. This approach helps compensate for variations in friction and thread conditions, giving a more uniform joint across fasteners. So the best description is tightening to the seating torque, then turning the fastener by the specified angle. Skip the angular step, and preload can vary; skip seating torque and the angle step, and you won’t reliably establish the correct clamp.
