These things, like all cheaply produced nuts, are random. They're great when they work, but half the time they don't rotate to lock in the profile when you tighten the screw. So don't waste hours installing any of them. Just get another one, hope it works better and try again. You're not doing anything wrong, these are nuts. Better ones rotate correctly when threading.
