He's my take on this.
One 3/8-24 fine thread grade 8 bolt dry torqued to 50 ft.lbs produces a clamping force of 7900 lbs. Torquing a 3/8-24 grade 8 bolt higher than 50 ft.lbs causes plastic deformation of the bolt. Plastic deformation causes the bolt to grow in length and shrink in diameter.
My guess is that reusing an already plastically deformed bolt is not recommended as the longer length may cause it to bottom out in the blind ring gear bolt hole and the bolt is weaken due to the decreased cross section.
