I have been looking at several different power distribution module designs and the all seems to use a large bolt for the main power input. I am curious what these connectors are called and how they connect to the PCB internally?

\$\begingroup\$ It's an earth bonding stud and not a power connector. \$\endgroup\$– Andy akaOct 19, 2020 at 16:53

Search for 'feed-through bolt terminal post'.

I know that sort of connection as a "terminal post". Many are designed to accept 4mm banana plugs, but not those. Many have a hole though the screw thread to push a wire through as well.
The threaded rod normally continues through the insulated base, so a ring terminal and locking nut can be used to make connection to the other end. My guess is that it would be connected to the circuit board by a short lead.

1\$\begingroup\$ @user8908459 - I'm in the UK, like Simon who wrote the answer, and "terminal post" is what I would call it too. Here are a few links to similar parts, called terminal posts by RS here and by Farnell here. However on Digikey, they seem to be called "binding posts", see here for that category on Digikey.com, and you can find similar components. Hope that helps. \$\endgroup\$– SamGibson ♦Oct 19, 2020 at 19:28
