Hi,
Almost no difference at all in steel, a change in diameter of about 0.0003", so you would not notice.
In aluminium, twice that.
Any competent lathe operator should be able to better + or - 0.005", but these are mass produced items and almost certainly are made on a CNC lathe, so I believe there is some other reason for the excessive clearances, if by design.
Cheers
