Concrete screw hexagon head ETA Opt 1

Our CE marked concrete screw is a powerful and flexible fastener for concrete. Cracked, uncracked or reinforced. The screw has a hexagonal head with flange and is inserted directly into pre-drilled holes without the need for a torque wrench.

The screw can be removed and reused allowing temporary installation.  
As the screw does not expand, it works well at short edge distances.

We provide the screw in the following surface treatments:

• Bright zinc-plated (BZP)
  
  
• Acid-resistant (A4) - The blue tip on the A4 screws marks the transition between stainless steel for corrosion protection and hardened carbon steel for better grip and easy installation in concrete.
  
  
• Atlantis (C3)

Concrete screw with Atlantis C3-H surface treatment, for dry indoor environments (50-year lifespan) or in C3 outdoor environments according to ISO 9223 (25-year lifespan). The concrete screw has fire rating R120.
