Flat Roofing and Decking screws are suitable for wood, concrete, insulation and metal decking due to the sharp drill point. Depending on the application, pre-dilling a pilot hole may be required.

  • Carbon steel is the most popular material for fixings as it is strong, weather resistant and affordable.
  • The pan head has a Phillips drive, ensuring easy installation.
  • The coarse thread provides excellent engagement with the substrate, maximising pull-out values.

For maximum fastener performance, we recommend using a tek screw driver which does not exceed 2500RPM.
