Thread on Recovery Point Bolts

I took the bolts off of my front recovery points (under the bumper, with the hook on one side and the loop on the other) and I seem to have lost them. Does anyone know the specs for length, size, and thread pattern for the 4 bolts?

Thanks

 

$13 M12x1.25 mm Self-Locking Nylon Insert Hex Lock Nuts, Pack of 6

M12x1.25 as for length I would have to guess 40to50mm

I would go at least the thickness of of the hook or what your bolting on plus 15 to 20 mm which most likely have you in the 40 to 50 mm range
