I had a read of Sheldon Brown, seems to be the way threaded headsets work, although the page did not have our particular models. I think all Mailstars have the grub screws but other models had the pair of locking nuts.

From what I can work out the nut at the top if for adjusting height while the collar is for adjusting the bearing race for smooth operation?
