They were a mild steel nut with a stainless heli-coil in it. If you can see that they are coming hard, DON'T BREAK A STUD. Instead, apply heat as already mentioned by others. If that doesnt want to work, a cold chisel applied parallel to the stud and partially split the nut. Use a 6 point wrench, not a 12 point. 6 points grip better. Orginal nut is 13mm, but for a rusted nut try a 6 point 1/2" wrench. It is just slightly smaller. If needed, try a 12mm.
