Brake caliper allen bolt size

[nevpat]

I need to do my brakes on my 87 XJ. There is an allen bolt on the calipers that is huge! I already have allen sets but not that size. Does anyone know the size so I can only make one trip? Much appreciated!

7mm I believe.

I've seen them with 8mm allen bolts too.
