I would use heavy duty crimp on ring terminals on that type of post.
I had to use ring terminals on the vertical threaded stud post on my current

in case you haven't read it.
Three boats ago the golf cart batteries I installed had a plain automotive post. I used crimp-on battery
post terminals [like these for example
] and they worked great. [In case you prefer terminal connectors...]
