Little thicker in upper portion than I thought, which is better than my observed guess, looking at the bolt, they look pretty close to being about 5mm bolts, which offers at least 1 diameter thread engagement in the top bolt, to get at the backside is a problem, you'll need small hands with some stuff removed to get a nut on the backside if you really felt you needed to, so I'd probably called it good enough here as well...
