Art,
Went to Sears and bought something called "Bolt-Out" by Craftsman. Too bad I bought it and used it at too late a stage for the hex head. I think it could have helped right away before I wore down the head. Doesn't work now. Anyway, I'm sure it works wonderfully for steel nuts and bolts.
Just want to clear up the technique on the heat. I can use a propane torch (plumbing). How long do I heat the bolt? Do I then tap the bolt with a hammer and then try to turn it while hot? Or do I let it cool somewhat and then try loosening it?
Also, for the wax technique, do I also heat up the bolt here and try to drip wax along the edges of the bolt and hope the wax gets soaked into the threads?
And, I have two more ideas. (1) Sacrifice my 13 mm box end wrench by putting it over the greatly diminished hex head (~10 mm now) and fill in the hole with something like JB Weld. Not sure if JB Weld "welds" together dissimilar metals such as steel and brass. (2) Or, try to have a friend come over and hot weld the wrench to the hex head. Will this last technique "melt" the tranny seals?
Thanks.
