Editing Removing stuck fasteners

{{youcanedit}}

==Summary==
A list of techniques for removing rusted or broken bolts, nuts, screws, and fasteners.

==The hot and cold method==
This method uses alternating heating and cooling. The resulting expansion and contraction is thought to break a fastener loose from the grip of rust.

#With a welding torch, heat up a bolt head until it turns red.
#While it's still red-hot, squirt it with water.
#Repeat the hot and cool process again with the torch and water.
#Turn out the bolt.

==Penetrating oil==

==Broken-off bolt heads==
#If enough of the bolt remains, try to grab it with locking pliers.
#Try to saw a groove in it, so that a flat-head screwdriver can be used to turn it.
#Take a 12-point socket that is just larger than the shaft of the bolt, and beat it down onto the bolt with a hammer. Turn it out with a ratchet. When done, put the socket in a vice, and tap the broken bolt out of it with a tap.
#If a bolt is broken off below the surface, built it up with a welder until there is enough to weld a nut to.
