I think 500.8(e) calls for it to be wrench tight. Thats a little ambiguous, but whats in the picture is far from hand tight.

If you click on the photo and zoom in, you can see the missing corrosion protection and exposed bare metal, albeit a bit rusted already. This is a new ATS installation using the existing RMC.
 
I think you got about two threads, what's permitted? The photo looks like black pipe instead of galvinized.

I have seen hubs with slot-headed screws in the package before, shouldn't have any points on the ends.
