Hi,
My first pinball machine, and my first time trying to maintain one - so go easy please
I've bought the set of Cliffy protectors for my TZ, and trying to install them. Naturally I've fallen at (almost) the first hurdle. Trying to take the slot machine wire rail off, and I'll be damned if I can actually unscrew the metal post with my fingers per the installation instructions.
Here is a photo (not my pin) of the post I'm trying to remove:

Will a regular small adjustable spanner do the job on that, or is there a better tool for the job?
Sorry for such a mundane question!
