That nut is always hot - fed from the 350 amp fuse on top of the battery.
From reports the nut is hard to remove without breaking the fuse box.
Why not slip a ring lug over the stud and add another nut? Be sure to fuse your new circuit and use appropriate size wiring.

No, I don't know the size except it is likely metric. You my just have to try a few different nuts and find one that fits.
It would be a good idea to disconnect the battery cables if you are going to be messing around the stud very much.
