Air vent hole. Meant to be open when transporting by air to allow the internal air to equalise with external air pressure. Otherwise kept closed on other occasions...especially when wet.
You don't need to completely unscrew it to all venting, just unscrew it around 1/2 a turn.
Edit:
Thanks for the measurements Eric.
