Aha, I see. Are you sure it's the screw head and not the allen key itself? I've rounded off a lot of them over the years. Also possible you've got the wrong key size (5/64" is just slightly smaller than 2mm...)
If it's the screw, you might be able to jam a SAE-sized allen key on there. (i.e. if your key is 2mm (0.0787") and spinning freely in the screw head, try a 3/32" (0.0937") allen key). Failing that, I've had good luck mashing slightly oversized Torx bits onto damaged allen-head (and Robertson) screws. You just have to try a few sizes to find one that'll grip.
