Another 3/8" stud bolt removed from the Fortress.  Notice how widely this unit has expanded.  Clearly, the walls of the hole that was drilled broke away allowing the bolt to expand well beyond the original confines.  In other words, the soft sandstone that this bolt was placed in could not resist the expansion of the bolt.
