The Stovebolt Site Forums The Shop Area General Truck Talk Also,what do you use on rusted bolts?

I use one of 2 methods as a rule.I either heat it up to a red and then loosen it while still as red as possible, or Iuse a disc grinder. If I use the disc grinder I prefer the zip cut wheel and cut from the outside in careful not to touch the material behind. If I only have a regular wheel ,I grind back and forth near the middle of the bolt, that way I have less chance of ruining the material behind.
