This function demonstrates the STEMFIE cam-locking connection. It uses a cam-locking pin and nut to join a brace to a beam. The fixed washer isolates rotational forces from the nut, thus preventing it from undoing the connection. Note that this cam-locking fastening is suitable for axially locking parts but allows for joint rotational freedom.
