Abstract

Screw, characterized in that it has a head at one end of a shank, a flange part that surrounds the shank and extends from it outwardly below the head, a maximum transverse dimension of the flange portion being in a perpendicular plane to the longitudinal axis of the shank greater than a maximum transverse dimension of the head in a plane perpendicular to the longitudinal axis of said shank, a covering element of synthetic plastic material molded around the head to cover the entire surface or upper surfaces of said head, at least part of the side of the same and at least one of the flange part an annular skirt below the cover element adapted to press by means of the lower side of said flange part against the surface surrounding a drill hole where the screw is housed, to form a water-tight seal between the covering element and the surface around the bore, the covering element having a part engageable to a key, of non-circular section in cross section perpendicular to the axis of the stem, so that the part engageable to the key can be picked up with an appropriate tool to rotate the screw.
