There is some excellent information in the article that kbinde2 referenced. For those who do not get that magazine, the article showed a technique for annealing the portion of the studs that gets swedged. The bolts are grade 8 which is too hard to swedge properly. There is a chance of warping or cracking the brake drums. The annealing reduced the area that is swedged to grade 2 but the rest of the bolt remains at grade 8. In my opinion, everyone should do this on reproduction bolts, especially the companies who are making them. They used a turntable (old record player) and heated the swedged area with a torch until dull red and then let them slowly cool. The author said not to heat too much or the bolt would get too soft in the swedged area.
