High-performance Sormat S-CSA+ HEX ML concrete screw with hex flange, manufactured in Finland. The carbon steel screw is cold-formed to provide a reliable fastener strong enough to penetrate even hard materials. The concrete screw features a hardened special thread that forms threads directly into the base material. The ML (Multi Layer) surface treatment is a corrosion-resistant three-layer coating (>1000 hours resistance in salt spray test according to EN ISO 9227), enabling significantly broader application areas than standard electro-galvanized screws. The screw is fully removable. Screw tensile strength: 800 MPa. Recommended for dry indoor environments and outdoor applications with consideration of usage limitations. The product has European Technical Approval ETA-20/0446 for concrete. The product is also CE marked. Fire rated up to R120 in concrete installations. The concrete screw is designed for through-installation. Installation steps: 1. Drill a hole according to product specifications. 2. Clean the hole thoroughly. 3.
