Light section screws fasten composite panels to cold rolled purlins (1.2mm – 3.5mm steel).

  • Carbon steel is the most popular material for fixings as it is strong, weather resistant and affordable.
  • Low profile heads provide a seamless finish with the material and are often powder coated to suit the panel. Low profile heads require T-25 bits.
  • The coarse thread provides excellent engagement with the purlin, maximising pull-out values.
  • The high thread has a wider diameter than the lower thread, so that the outer sheet is well-engaged.
  • The no. 2 drill point is designed to maximise accuracy whilst ensuring a clean cut through up to 3.5mm steel, without burn-out.

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