Heavy section screws fasten sheet metal to hot rolled purlins (4.0mm – 12.5mm 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 fine thread provides many points of engagement with the purlin, maximising pull-out values.
- The no.4 drill point clears 4.0mm to 8.0mm steel. 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.
