How to Remove a Rusty Nut or Bolt
Posted: Sun Dec 26, 2004 9:49 am
I know this is elementary to most, but a few may need the knowledge and most might learn one more technique. Here are a few suggestions:
- Soak in penetrating oil (Liquid wrench, Marvel Mystery Oil, diesel fuel, WD40, oil of wintergreen, bore cleaner). Allow time to work. I like to soak the rusted fastiner once weekly for a month or two with diesel fuel.
- Gently hammer the proper sized bolt out from Sears, Irwin, Home Depot and twist counter clockwise.
- If broken off then stud remover (if stub is long enough) or spiral extractor, or multispined extractor after drilling proper sized hole.
- Heating with torch then applying penetrating oil when warm not red hot.
- Burning the nut off with torch.
- Using torch to weld another nut.
- Striking the bolt or nut with hammer and with medium force then more penetrating oil.
- Cutting groove in nut with dremel and then enlarging groove with chisel and then more penetrating oil.
- Cutting off nut with cut off wheel.
