(OP)
Overtightened bolt.
Looks like a typical overtightening.
The nut has galled.
Ideas?

RE: another bolt fracture
is the bolt securing 2 substantial metallic components together?
is a gasket involved?
Are the complaints of the fasteners loosening?
If other's comments regarding fatigue indications are correct, it looks to me like part of the problem may be that the bolt is not being installed to provide the preload it is capable of providing.
It might be as simple as adding some nice thick flat washers to the Bill of Materials and adding a torque spec ( boooo ! hisss! ) to the assembly sequence.
