Abstract
A self closing cover for the head of a screw is integrally formed of a resilient polymeric resin and includes a flat annular washer having upwardly projecting closure flaps along its periphery and connected to the washer for swinging to interfitting dome defining positions overlying the washer. A flap closing finger depends from each of the closure flaps and with the tightening of the screw toward a work surface, the work surface bears on and swings the fingers to swing the flaps to their closed positions.
