Abstract

The screw or plug has an axially symmetrical star or cross shaped hole (7) in its head for containing a matching-shaped cross-recessed headed first screw driver. The drive piece in the head of the fixture, coaxial with the star or cross-shaped hole, has an additional multiple-grooved hole (5) for containing the matching multiple-grooved piece of a second screw driver. The multiple-grooved hole is formed of radially outward pointing circle arc-shaped cavities (25,27) positioned near arms (17,19,21) between the slits (9,11,13,15) of the star or cross-shaped hole. A bar (39) radially protruding towards the centre of the multiple grooved hole is positioned between two adjacent cavities.
