The FEX screws have been specially developed for the production of windows. With these, SPAX offers a closed range of screws for a wide variety of applications in window construction. The range of FEX is divided as follows:
FEX: the fitting screw
Is suitable for attaching fittings to wooden profiles, as well as to plastic profiles without steel reinforcement. Thanks to its CUT tip, it effectively reduces the formation of gaps in wooden profiles.
FEX-A: the window drill screw
Is suitable for attaching steel reinforcement to plastic profiles as well as for mounting fittings on single-walled plastic profiles with steel reinforcement. Thanks to its drill bit, it ensures optimum drilling performance, both in manual and automatic operation.
FEX-KS: the screw
Has been developed for the attachment of fittings to plastic profiles without steel reinforcement. Due to its special geometry, it can be processed without pre-drilling the plastic and ensures a solid hold.
FEX-RS: the roller shutter screw
Has been specially developed for the fastening of roller shutter profiles. Despite its short size and thickness, the screw does not need to be pre-drilled. A special needle tip allows a clean and fast screwing in of the screw. The screw is available for the most common profiles.
FEX-H: the wooden window screw
Has been developed for fixing window fittings in classic wooden window frames. It impresses with a 4CUT tip which offers a clean and easy penetration into the wood and reduces the screw-in torque.
FEX: Combi screw
Has been developed for the fastening of fittings and corner bearings for fastening in plastic windows with steel reinforcement. It impresses with a drill tip and two consecutive thread types. In the upper area it has a coarse thread (for plastic) in the lower area a fine thread (for metal).
