The HECO-UNIX-top Cladding Screw with contraction effect

Timber façades are becoming increasingly popularin both new builds and renovations. This applica-tion places high demands on fastenings. The façade must be securely fixed to the sub-structureand the fixings should be invisible or attractive to look at. In addition, the structure must be permanently sound if it is constantly exposed tothe weather. The HECO-UNIX-top façade screwis the perfect solution to all of these requirements.The full thread with its variable thread pitch reliablydraws the façade boards onto the sub-structurewithout the head having to be countersunk deep

into the timber. The façade is secured axially viathe thread, which increases the pull-out strength.This results in fewer fastening points and an ultimately more economical façade construction.Thanks to the full thread, the sole function of the head is to fit the screw drive. As such, the HECO-UNIX-top façade screw has a small raised head, which allows simple, concealedinstallation preventing any water penetrationthrough the screw. The screws are made ofstainless steel A2, which safely eliminates the problem of corrosion caused by exposure toweather – for instance, rusting screws.
