Heavy section screws fasten sandwich panels to hot rolled purlins (4.0mm – 12.5mm steel).

  • Stainless steel provides excellent corrosion-resistance which increases the life-span of the fixing.
  • 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 fine thread provides many points of 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. 5 drill point is designed to ensure a clean cut through up to 12.5mm steel, without burn-out.

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