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

  • Stainless steel provides excellent corrosion-resistance which increases the life-span of the fixing.
  • Hex heads are standard across the industry, and require a 5/16″ socket, which we also supply.
  • The fine thread provides many points of engagement with the purlin, maximising pull-out values.
  • 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.
