Steering column collar and hub

Searched and came up empty, so this the official HELP post...

How in the tar nation does one reassemble the steering column collar and hub so the hub is “locked” in position and will not turn?

I have put this thing back together as I took it apart...or so I thought.

Why do I think my issue has to do with those 2 little square head bolts that I can’t figure out exactly what they do?

This is making me coo-coo for Cocoa Puffs!

Thank you in advance for any help/hints.
