Yes. Screwdriver
Looks like someone forgot to remove their chewing gum from the mount before packaging it.
keep it while travelling..i had to keep tightening it every day to prevent it getting loose and spinning
My guess would be that it's used to tighten the screw into the camera.
And your guess would be absolutely correct.
