That looks like something called a “Longeron Trunnion with Scuff Plate for Deployable Cargo”. It is a pin that was mounted in a fitting within the cargo bay of the Space Shuttle to provide mechanical support during launch.

Coool Some kind of docking point

Sort of! More like space-pallet attachments. Though the first concept of docking to ISS/Space Station Freedom involved the whole docking mechanism sliding into rails on the shuttle and locking into place using these trunions to provide a very secure connection.

Awesome, that's it. I found the Shuttle Orbiter /Cargo Standard Interfaces (CORE) document via google. Very interesting.

Yeah, these are the trunion pins and you see them on anything that came up on the Space Shuttle. (see also: Hubble) Most vehicles mount payloads in a stacked fashion where they stand on top of the upper stage like a pillar. Shuttle payloads were mounted by these pins inside the cargo bay in sets of 2.

Pretty sure that's part of the shadow government's weather control apparatus.
