You're absolutely reasonable! The tech's story is the bolt never hit anywhere near the torque spec, implying a pre-existing issue. The shop owner was thinking the threads could have been damaged when the bolt was broke loose during disassembly. This is like a frozen bolt pulling the threads with it. Problem here is the rod's threads "above" the bolt's thread pattern were perfect. I would think if threads were truly frozen on the bolt then the bolt would have dragged those frozen threads right through all the rod's threads and buggered them all.
