thread is a total afterthought of a broken bolt in something else altogether. it just made me think that I haven't seen a recent thread on this in a couple of boards I read.
So, if we need a scenario, how about a broken head bolt? Bolt is inside the block bolt hole (to deep to weld), broken off uneven? I'm sure at some point we all go through this on something, automotive or not. If you have a great extractor tool, show us your weapon!
