Lots of links in the threads for 12 ga. wiring but I have not found a source for heavy duty high temp flags. I did find high temp flags online but none of them heavy duty except for manufacturer sites. https://www.amazon.com/Supco-Female-Disconnect-Temperature-Degree/dp/B0071NCA48?th=1
Note in the comments in the amazon link that many of these high temp terminals are still thin and at least one commentor went to a oil drilling business to find heavy duty high temp ones. As many of us who have seen the melted terminals first hand, heavy duty seems the direction to lean towards beyond just installing high temp terminals.
apparently there are two grades of high temp flags.
