Well, you tune as closely as you possibly can with the tuners before you lock the strings at the nut. You then check the tuning again and adjust the fine tuners as you see fit to get as close as you can to the desired tuning.

Basically, they are what they're called. Fine tuners.

Well they...fine tune. So if the strings go a little bit out of tune while playing, which they will, instead of having to undo the floyd rose you can use the fine tuners to tune it.

they allow you to tune when the locking nut is locked because the locking nut usually pulls the strings slightly out of tune- the fine tuners will let you "fine tune" it after the nuts locked

Actually when i play with my hardtail strat i find myself trying to grab something on the bridge to tune the guitar.
They just let you fine tune
