CONC SCREW SORMAT S-CSA+ HEX 14X150 SW21 ML COATED 10PCS

High-performance Sormat S-CSA+ HEX ML concrete screw with hexagonal flange, manufactured in Finland. The carbon steel screw is cold-formed to provide a reliable fastener with sufficient strength 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. Concrete screws also have the general DIBt type approval Z-21.8-2136 for temporary fixings in concrete, enabling reuse for temporary applications such as formwork installation. Measurement determines whether the screw is reusable, performed using the inspection gauge CG S-CSA+ 14. 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 material. We recommend using a suitable-sized impact screwdriver for installing concrete screws. No preset torque value. Usage allows for small minimum edge and spacing distances between anchors. Pack size: 10 pcs. The screw has a partial thread with thread length of 112 mm.
