Hi folks,
Yes, galling IS the transfer of metal.
Try this test--->
Take two cubes of butter, one in each hand. Put them flat side against
each other and rub.
That is what's happening to the metal when it galls. I have had bolts gall
so bad that they were virtually WELDED in the hole. After using
anti-seize, this is practically impossible.

ps - If you do the butter test, I will deny that I ever told you to do this
when your spouses call.
