Installation instructions Decking screw

Decking screw (external) for wood stud

  • Function: Sharp tip and threads adapted for anchoring in wood. The threads immediately grip and tighten the screw to the decking, while the grooves underneath the head sink the screw. Suitable for installing decking, balconies, fences etc. The unique tightening features of the screw have been achieved by providing the screw with a cutting drill tip, as well as with oblique and longitudinal flanks between the threads. This provides the following benefits:
    • Less risk of cracks in wood.
    • Lower torque when tightening.
    • Less screwing time.
  • Drive type: TX 20.
  • Material: Case hardened steel.
  • Surface treatment: Zincotech Au, type approved for corrosivity class C4, no. 0168/07, for outdoor use.
  • Installation instruction: A power screwdriver with depth stop is recommended, countersunk head approximately 2 mm.
  • Dimension: About 30 pcs/m².
