Sormat S-CSA I A4 concrete screw manufactured in Finland with detachable M8/M10 internal thread. The anchor body, cold-formed from acid-resistant A4 steel (1.4401), combined with a carbon steel tip, ensures secure anchoring even in hard materials. The concrete screw features a hardened special thread that forms threads directly into the base material. Surface treatment is electroplated zinc coating (? 5 µm) in accordance with EN ISO 4042. The screw is fully removable. Recommended for indoor, outdoor, and industrial environments. The product has European Technical Approval ETA-22/0413 for concrete and is CE marked. Fire-rated for concrete installations up to R120. Installation steps: 1. Drill a hole according to the product specifications. 2. Clean the hole thoroughly. 3. Insert the screw through the material to be fastened until the anchor flange contacts the surface. The anchor can also be installed directly into the substrate without the fastened component.
