Stainless Steel Countersunk Composite Panel to Light Section

For fixing insulation panels to cold rolled purlins (1.2mm – 3.5mm steel).


This standard anti-corrosion coating ensures our fasteners can withstand over 500 hours in a salt spray test. It is a specialist epoxy zinc and aluminium compound which produces a multi layered, scratch resistant coating. Countersunk heads lie flush with the surface of the substrate. They generally have a torx drive.

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

  • Stainless steel provides excellent corrosion-resistance which increases the life-span of the fixing.
  • Countersunk heads lie flush with the profile, and require T-25 bits.
  • The coarse thread provides excellent engagement with the purlin, maximising pull-out values.
  • 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.
