C.5 YIELD

The YIELD ValueTag is intended to denote the point where the material in the bolt goes beyond the state of elasticity and therefore undergoes plastic deformation, causing it to become permanently elongated.

The yield point is usually the area where the linear growth of torque versus angle is dropping.

Example: The picture below represents a tightening until the bolt breaks.

Just like SNUG, a YIELD point is difficult to calculate exactly, and the tightening system will report an approximation.
