摘要
The invention relates to a metal or plastic closure screw (FIGS. 1 to 9) and a housing section (7) made of metal or plastic with a corresponding housing bore (FIGS. 7 and 8), which is inserted through the locking screw (FIGS Fig. 8) can be closed, wherein the closure screw (Fig. 1 to Fig. 8) is designed as a countersunk screw, and in which a flat ring seal (6) below an external thread (3) is located on a fixing device formed by two shaft portions The flat-ring gasket (6) is located on the one shaft region (4) which lies further in the axial direction, and by means of an axially underlying shaft region (5) with a greater maximum radius than that of the overlying shaft region (4), the flat-ring gasket becomes (6) taken from the threaded hole (8) by the top of this shaft portion (5) when unscrewing the screw plug (Fig. 1 to Fig. 9) and safely removed. The closure screw (FIGS. 1 to 3) and the flat-ring gasket (6) thus form a unit (FIGS. 4 to 6). The threaded bore (8) corresponding to the closure screw (FIGS. 4 to 6) with a flat-ring gasket (6) ) includes an axially underlying approach (10) formed by a bore (9) with a smaller diameter than that of the threaded bore (8) in the axial direction below the threaded bore (8), and on which the flat seal (6 ) is pressed or squeezed by tightening the locking screw in a predominantly axial direction (12).
