OT: Tow-bar ball nuts and bolts...what size spanner?

Fab Foodie

hanging-on in quiet desperation ...
Gotta remove the tow-bar ball on my car to remove the bike rack fixture that is bolted to it. 'Cos of all the sockets and wires it's a bugger of a job to do with adjustables and stilsons, sockets would be good or the correct type of spanner, but oes anybody know the size required?

Cheers
