Still not sure why it did that because there really doesn't seem to be ANY taper in the screw.
If you've ever made mating Acme screws you would know just how oddly they fit together. The tiniest change in pitch diameter or thread form can be the difference between binding up, smooth fit or just plain wonky fit. The nut now sails from end to end on the screw and there's no measureable difference in clearance anywhere.
