Fitting for window or door comprises passage holes for fixing screws in two different angular directions and housing receiving screw head has two support surfaces at angle to each other

摘要

The fitting comprises passage holes for fixing screws and a reception zone for the axial screw head. For mounting the fixing screw in two different angular positions of the screw axis, the housing receiving the screw head comprises two screw head support surfaces (24,25) forming an angle ( alpha ) between them. The support surfaces are directly adjacent partially circular annular surfaces (27,28). The hole (13) passing through the fitting has two drillings (19,21) whose axes cross at a point of intersection (23) in the zone of half thickness (D).
