[Walt Fricke]

Yes - double nutting. Screw one nut down about one nut's width below the top of the stud. Screw another on top of it. Hold one, tighten the other against it. Then use an open end wrench to turn the bottom nut counter clockwise. Slower than a good stud puller, but does the job.

If you find one doesn't want to come out despite persuasion, you might consider leaving it as a reward for its tenacity. Otherwise you risk breaking it off if you just keep upping the torque.
