Torque + Angle is a method achieve a pull on the bolt that is more precise than torque alone.
A Torque + Angle procedure by itself does NOT indicate a torque to yield condition.

This is not the case. The point of torque to yield is to achieve the maximum possible clamp load from a bolt. The bolt ends up permanently deformed, but the torque to get to that point is always increasing.
