If it's that...
then just screw it in
- like you would use a screwdriver to drive a screw.
With a strat type trem (and most others) pushing down on the bar lowers the pitch of the strings , pulling up raises the pitch . Fiddle about with it and see how far you can go .if it F**ks up your tuning too much ..ask us again..
Good Luck..
Accuracy,you say? hmm interesting concept..
