Screws - Self Drilling with Wing - Wingteks

Wing Teck Screws are specially designed for fastening timber to metal. The special wing feature prevents thread engagement with the timber enabling rapid fastening without stalling or lifting of the timber before the screw has fully penetrated the base material.

As the drill point drills through the timber the special wings enlarge the hole diameter ensuring that there is clearance between the threads and the timber.

Once the drilling point has fully penetrated the base material the special wings break off on contact with the base material. The threads on the screw shank then engage and cut mating threads into the base material. The fastener head is then recessed into the fastened material as the required clamping forces are generated.
