Concrete screw Truss head ETA Opt 1

Our CE-marked concrete screw with a Truss head is a powerful and efficient fastening solution for concrete—cracked, uncracked, or reinforced. The screw has a large rounded head and is installed directly into pre-drilled holes without the need for a torque wrench.

The screw can be removed and reused, making it suitable for temporary installations. Since the screw does not expand, it works well in applications with short edge distances.

We offer the screw in the following surface treatments:

- Zinc-plated, FZB

- Acid-resistant A4, Blue Tip – The blue color marks the transition between stainless steel for corrosion protection and hardened carbon steel for better grip and easy installation in concrete. The body of the concrete screw is made of A4 stainless steel, while the tip is hardened carbon steel.

- Atlantis, Corrosivity Class C3

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