The nut is 10mm and the allen head bolts are 3 mm. You just need some 1/4" extensions and universal 10mm socket, shallow drive. I also sometimes use a little 10mm wrench I cut to be the right size and then ground down to be the thickness I needed. Don't recall why I cut it so it is open, must have used it on a fuel line or something.
