In most instances this wouldnt be a big deal, either drill/cut the head off the bolt or slot it for screw driver removal. But alas the bolt with rounded out allen hole is located inside the BB shell of a Fisher CR-7. One bolt was partially stripped but I was able to pound a slightly larger english allen key into it and remove it that way. But bolt #2 looks like it will be a permanent fixture rendering me unable to disassemble the frame.
