Concrete screws fasten steel to concrete. Predrilling a pilot hole is required for our concrete screws.

  • 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 concrete, maximising pull-out values.





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