Help with Hipshot GB7 drop tuner installation

[missis sumner]

I managed to buy one off Ebay, and got it on the bass but I can't adjust the screw enough to bring the drop tuning up to D?  The highest it will go is C sharp.

I've attached links to two photos.  The first is in the E position, the second is in the dropped position.

Have I installed it correctly?

Do I just need a longer screw?

That doesn’t look like the original screw, it should be much longer and have a knurled head for adjustment.

Oh, bugger.  It appears to be an odd thread, as well.  I've tried four slightly longer ones, and although they will wind in a bit by hand, they stop a couple of turns in.

I’ve found Hipshot to be a very helpful company, email them and see if they can supply a spare screw.
