Try Penetrating Oil

Spray the nut with penetrating oil and let the oil sit for 10 to 15 minutes to penetrate the threads of the bolt. Then use a wrench to try and loosen the nut.

Hold a hammer against one side of the nut, and hit the other side with a second hammer. That might loosen the nut so that a wrench can remove it.

Try a Hacksaw

If the nut is badly rusted, pour hydrogen peroxide on it to dissolve the rust. If that doesn't work, saw through one side of the nut with a hacksaw. Then loosen the nut by twisting it with an adjustable wrench.

Cut a Groove

If the head of the bolt is buried in your work piece, use a hacksaw to cut a groove in the top of the bolt. Stick the end of a screwdriver into the groove to hold the bolt steady while you loosen the nut.
