There are no 1.5 screws on a sledge so you don't need that size. 2.0 and 2.5 should cover it for hex drivers.
I've found on mine that the sockets are hard to access with a socket driver, so I just grab them from the side with some needle nose pliers (Leatherman Wave to be specific) and that's worked well for me.
I don't remember if there are any 3mm that I have found yet. And yeah, I put a set of small open ended and box wrenches in my tool bag, if I can't get a nut driver on it.
