Definitions
1
The technique — and by extension the torch itself — of heating a rusted or seized fastener red-hot so the metal expands, breaks the corrosion bond, and finally lets you back it out. Not the same as cutting it off; the goal is to save the threads. Every mechanic and millwright has a hot wrench story.
“Give that nut a couple seconds with the hot wrench and it'll spin right off.”
