CONC SCREW SORMAT S-CSA HEX 6X70/15/30 ML COATED 100PCS

Sormat S-CSA HEX ML concrete screw manufactured in Finland with a hexagonal flange and Torx drive. 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 its own thread in the base material. The surface treatment is ML (Multi Layer), 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. The 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-16/0945 for concrete and ETA-17/1009 for series fastenings into concrete and pre-tensioned hollow core slabs. The product is also CE marked. Fire rated for concrete installations up to R120. The concrete screw is designed for through-installation. Installation steps: 1. Drill a hole according to product specifications. 2. Clean the hole thoroughly. 3. Insert the screw through the material to be fastened until the anchor flange contacts the surface. We recommend using a suitable size impact screwdriver for installing concrete screws. No preset torque value. The design allows for small minimum edge and spacing distances between anchors.
