Very quick question about Fender bullet truss rods

[sockdeluxe_mike]

Title says it all really - I have a Marcus Miller jazz bass and I'm not sure what size allen key I need to adjust it properly? Are they very readily available in packs? I have a key very similar to the size which doesn't slip fine when I loosen it but it would tear the nut to shreds if I tried to tighten with it
