21 October 2013

Prodomaniatly used for decking or flooring when timber,decking,ply or modwood needs to be screwed directly to steel bearers joists or purlins.

Timber to Metal Wing Teks. Stainless Steel and or Galvanized.

Wing Teck Screws are specifically designed for fastening timber and composite boards to metal with no pre drilling or countersinking. The special wing feature prevents thread engagement with the timber enabling rapid fastening and stops the lifting of the timber before the screw has fully penetrated the base material.

As the drill point drills throught the timber the special wings enlarge the hole duiameter ensuring that there is a 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.

These screws are Bi-Metal as they have a high tensile drill tip fused onto the stainless steel screw and then are class 3 coated (galv) to protect the tip. A reasonably fast screw driver 2000 rpm Minimum is recommended and will drill through about 3.2mm thick steel.
