Fibre cement screws fasten fibre cement sheets 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.
  • Hex heads are standard across the industry, and require a 5/16″ socket, which we also supply.
  • The coarse thread provides excellent engagement with the purlin, maximising pull-out values.
  • The no. 3 drill point is designed to maximise accuracy whilst ensuring a clean cut through up to 6.0mm steel, without burn-out.
  • Baz washers come as standard, ensuring a secure seal on corrugated panels.

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