Deltafix chipboard screw flat head / torx / nibs / type 17 screw point galvanised 4.0 x 40 mm 250 pcs

Galvanized steel chipboard screws with flat sunsen torx head are extremely suitable for attaching wood and sheet material. With this type of screw, the thread continues up to 30 mm length to the head. From 40 mm length is the Deldraad. Two pieces of wood attract more easily with the use of the Deeldraad. The coarse winding and sharp intersections ensure that the screw is easy to turn in the wood, so pre -drilling is often not necessary. Through the flat head with milling ribs, the screw is galvanized in the material.
