why are you using 1/2 13 bolts to attach a skid plate? that's way overkill.
3/8 is fine, 7/16 is more than enough. remember pressure on a skid plate is going in two directions, neither of them will be pulling down on the bolts and shear forces won't be too significant if you don't catch an edge on anything(which you shouldn't if you designed it well).
