An impact or air wrench would be helpful, but I don't have either. Instead,
I've got the best impact tool ever -- a hammer! The shiny wrench is thin
enough to hold the hex end of the rod through the hole in the black socket.
Insert a spare bolt into the side hole of the socket, whack it a couple of
times -- and the nut moves!
