The replacement nuts are made from steel while the good OEM nuts were
brass with chrome plating. Brass has a similar expansion rate to
alumininum .
The collapsing I made reference to was the force imparted not actual
collapsing, but the distortion is often permanent and it does limit the
effectivness of the nut.

Greg, the two are made from different metals. The aluminum expands at a different amount/rate than the nut. So I do it once cold and then again hot (gas stop). After a couple gas stops, even with antiseize, there is not tightening to do. This summer after 2000 miles I checked again, no loosening, tight as ever. And on these parts (heads and nuts) the threads were not in the best of shape. I do use the frame rail clamps as well though. And I seriously doubt a hook wrench is gonna collapse anything. unless there were other problems present already.
