Fastening aluminium and steel profile sheets to aluminium and steel.


(Recommended) processing method

1. Insert the screw with increased pressure and low rotation speed (approx. 200 revolutions)

2. Pressure can be reduced as soon as the thread engages. The rotation speed can then be increased to approx. 1600 revolutions.

3. Immediately before fitting the sealing washer, reduce the rotation speed considerably and tighten the sealing washer until it is slightly compressed.

4. Recommended tightening torque for steel substructure approx. 3 Nm, 1 Nm for material thicknesses under 0.8 mm.

Recommended tightening torque for aluminium substructure approx. 1 Nm, 0.5 Nm for material thicknesses under 0.8 mm.
