Tough Bolts

Authored by: Nepherim

If the nut is completely stuck or rusted on the bolt, try one of these methods. Note that the methods become increasingly destructive, so use with caution:

• Drench it in PB Blaster, or WD40, or some sort of penetrating oil. A 24 hours wait might help!
• Use an extension on your wrench; this is usually not good practice with a ratcheting wrench. For example, use a 10-18 inch piece of pipe slid over your lug wrench to losen your lug nuts. Should take 1/4 the effort of a normal wrench.
• Use an impact wrench; usually air powered, available at any mechanic shop.
• Some nuts/bolts have a hex key slot cut into the head, which may be easier or more effective.
• If you have access to a propane torch, and the bolt is in an accesible area, you can try heating the nut, which should make it expand, and thus easier to remove.
• Drill out the top of the bolt, and use bolt extractor (available at most tool stores, and Sears).
• If the nut is totally stuck and you are able to replace the bolt, try tightening the nut until the bolt snaps. Alternatively just use a dremel or hacksaw and cut the bolt.
