Sormat S-CSA I ML concrete screw manufactured in Finland with detachable M8/M10 internal thread. 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 surface treatment is ML (Multi Layer), a three-layer corrosion-resistant coating (2016 hours resistance in salt spray test according to EN ISO 9227, corresponding to corrosion class "C3 very high" per DIN EN ISO 12944-6:2018-06). The screw is fully removable. Tensile strength of the screw is 800 MPa. Recommended for dry indoor environments and outdoor applications with consideration of usage limitations. The product has European Technical Approval ETA-17/1009 for anchoring into concrete and precast hollow core slabs. Based on this approval, the product is CE marked.
