The flooring screw keeps all chipboard elements in place on the subfloor, regardless of the forces exerted on it. This is possible thanks to the separate fixing thread below the screw head. When installed, this thread sits inside the flooring panel, preventing it from moving even under heavy loads, preventing squeaky floors. The SPAX floor board screw is ideal for laying solid wood flooring: the arrow-like CUT point slices into the material and the milling ribs below the head ensure smooth countersinking. The small flat countersunk head effortlessly pulls the board onto the substructure without getting in the way of the tongue-and-groove connection.
