Default Properly Screwed-Together Beetle

"Many innovations in modern mechanical engineering were taken directly from nature, like the ball-and-socket joint, which was first described as part of an organism’s anatomy before being adapted as a machine. The classic screw-and-nut system, however, was thought to be a uniquely human innovation. Now, researchers have found an example of this screw-and-nut system in the legs of a beetle known as the Papuan weevil, Trigonopterus oblongus. (Apparently, evolution beat us to the punch on that one as well.)"

Odd things...
Do they pivot or screw their legs tighter and looser to walk?

Aparently not. That specialized joint mechanism appears to allow them to position their legs in a particular resting mode.
