I'm in the process of making my 2 pt bridge flush instead of floating. The problem is now my action is too low so I fret out while bending high up on the neck. I need to raise the saddles but I don't have that small allen wrench to make the adjustments

so does anyone know what size I need? The guitar is an american deluxe. The one I use for my MIM standard is just a tad to big and won't fit it. Please help! Thanks!
