You never mentioned an easy out? Is that the the same as an extractor? An easy out screws into the existing screw in an outward fashion. removing the bolt as it drills. These are virtually fool proof. But they have a copyright. It must say easyout!. anything else , well will prolly fail. If all else fails grind drill ,retap and be done with it. As for damage on a 6 sec run? uh, not a chance, there was no way temps could run high enough too create wear. High heat kills mechanics nothing else. Ya can runa motor on no oil longer than that, and come away a winner. but let's not go there lol.
