Despite that being true, heat directly applied to the bolt by arc welding works well. I have never had any damage by arc welding nuts on. The heat also helps to loosen it but will make it lose its temper and be soft. Never had much luck with stud extractors. Usually can't get them aligned. Just a thought that a drill guide might help.
