Medium section screws fasten sheet metal to cold rolled purlins (1.5mm – 6.0mm 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.
For maximum fastener performance, we recommend using a tek screw driver which does not exceed 2500RPM.
