Carbon Steel Countersunk Concrete 

For fixing steel to concrete.


Countersunk heads lie flush with the surface of the substrate. They generally have a torx drive. 

Note for powder coating, the fixings are blue so dark colours are recommended

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.
  • Countersunk heads lie flush with the profile.
  • 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.
