You are right. The tensile strength of a AN bolt is about the same as a grade 5 bolt. However the biggest factor is that normal grade 5 and 8 bolts are designed for more of a tensile loading setup while an AN bolt is designed more for shear and is more flexible and has a much better fatigue factor.
