While I agree with your method of removing the case studs, I'll have to disagree with your assessment that the temperature of the stud and the adjacent case are at the same temperature.

If the stud is heated to a dark red to cherry red color to break the Loctite bond, that equates to a temperature range of 1200-1600F. Aluminum or magnesium alloys melt around 1220F. If the metal surrounding the stud is the same temperature as the red hot stud, the case would melt. However, it doesn't. That's because of the heat transfer characteristics of these non-ferrous metals and the heat sink property provided by the hunk of crankcase metal.

Interesting discussion. As Wayne mentions, there's more than one way to skin a cat. Readers now have a choice to try on their case studs. Thanks for looking at it from different angles.

BTW, rapidly cooling the stud (quenching) and/or slowing the cooldown rate (annealing) will change the molecular characteristics of the stud.
