Turbo screw ( Window frame ) ZnB

Description:

The Turbo screw is a special flat-head screw ( up to 302 mm long ) for low-cost installation of window frames without inserts. The flat head design is particularly suitable for aluminium and plastic window frames. The small bore diameter of 6 mm and the screw-tightening without cleaning the bore allow an efficient series fixing. The high thread on the screw tip and the milled ribs reduce the tightening torque and allow energy-saving installation. The continuous special thread prevents the window frame from dragging against the substrate. This means that the frame is fixed to the building material without tensile force or tension.
