The screw length that need to be used for panel installation depend on the panel thickness
and is based on the following formula:
5mm ≤ l - t ≤ 8mm
l = length of the screw
t = thickness of the panel
Use the screws and metal washer included in the box for standard panel thickness of up to 3mm. For
thicker instrument panels, use longer screws and use the formula to choose the right screw length.
