CONC SCREW SORMAT S-CSA+ HEX 8X70/5/20 ML COATED 50PCS

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 into 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-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. Insert the screw through the material to be fastened into the hole until the anchor flange contacts the material to be fastened. We recommend using a suitable size impact screwdriver for installing concrete screws. No pre-defined tightening torque is specified.
