I want to tune my Schecter guitar to Drop B ( B F# B E G# C#). I know that when you change tunings you must set the bridge springs so that it levels with the body. The thing is that when I tune to that tuning, the bridge doesnt level up with the body. I try to loosen the spring's screws but it just slaps back and I have to re-screw all again, I worried that I damage the screw holes. What can I do?

P.S. That guitar is awesome but its a pain in the butt when it comes to tuning. It should be a one only tuning. It takes about minutes or more to tune it. Overall nice guitar.
You could just block the trem if you change tunings lot
