Very poor quality in the piece of wood. The wood selector for the day that cue was built was sleeping on the job.
The break shows signs and characteristics of a spalted (rotten) piece of wood. A healthy piece of wood very rarely would exhibit a clean, straight across break that is shown in the picture.
The bolt did not break. It broke at the end of the bolt cavity which further weakened the dowel with an improper construction design.
I think this is spot on. The break occurring at the end of the bolt is no surprise when coupled with what appears to be bad wood.
