Added (1). Thanks Brittany, but don't see any relevance to my question, just a bunch of unrelated links.

Hi these tend to be the larger ones not supplied in most sockets sets 25 mm or similar are what you need just measure it with a steel rule.

Yes, its whichever one goes over the bolt with a snug fit.
