WOOD SCREW PROF CS C4 T20 4x40 200pcs

Precise T20 drive that enables one-handed screwing. Specialized fluted base that leaves a smooth and clean finish. Specialized tip immediately grips wood and is also suitable for plugs. Less common thread than standard wood screws provides faster driving. Cutting groove along the entire thread length breaks fibers, thereby reducing friction. Milling thread after the main thread reduces stress while increasing compression. Made from toughened 10B21 steel. The screw withstands bending and torsion well. CE-marked based on ETA assessment, approved for load-bearing timber structures. Packaged in weather-resistant two-part cardboard box. Not recommended for attachment to pressure-treated wood and spruce. • 200 pcs/package • Base diameter 8 mm This product description is an automated translation of the original Finnish description.
