Re: torque spec?

Attaching the nut by only 1-2 threads has probably increased any effective 'resistance' the terminal has as well. If you overloaded the terminal with 120A, you would probably severely damage something, or really burn someone's hand if they touched it at the wrong moment. The point is -- it can't stay like that.

I'm also surprised the bolt snapped before the PCB cracked. I wonder if there are stress fractures where the stud connects to the PCB...which would again significantly increase the resistance of this terminal.

Sure, you can 'patch' it with a standoff as mentioned above, but for safety and reliability reasons, I would get a new one.
