Heat helps for steel in steel situations. I think for steel in aluminum or magnesium the case will produce your effect. Maybe a few days of applying penetrating oil and tapping the stud with a metal tool lightly before actually trying to unscrew it would help. Anyhow, I had to grind mine flat, drill out the center, and use an extractor. Then I used a helicoil too, even though the threads looked okay.
