It also depends on whether you use a plastic nut, or bronze? Lubrication? An anti backlash nut will cause a little more friction. The sample plastic nut I tapped myself seems to get looser the warmer it gets.(expansion?) Just by holding it in my hand for a few minutes. I haven't actually used it, though.
