Heco TOPIX-plus plank screw raised countersunk head with milling ribs TX fully threaded 3.5x50 mm

The HECO-TOPIX-plus floor screw pulls the wooden components together and simultaneously fixes them axially via the thread. This not only allows for quick and cost-effective assembly but also reliably prevents annoying squeaking of the wooden surface at the screw shaft. Since the loads are transmitted through the thread, the head serves only to accommodate a drive and can therefore be designed to be very small. It can be used space-saving in tight installation environments of tongue and groove and does not protrude into the adjacent component. This ensures a precise connection of the profile timbers. In addition to the head and thread, the HECO-TOPIX tip offers another advantage when processing tongue and groove: The patented HECO-TOPIX drill tip reduces splitting effects, making it possible to use it in very thin cross-sections with minimal edge distances.
