Can I put a nail or a screw in my Novagrip/Compositube handle?

It is not possible to put a nail in the Novagrip handle. However, you can put in a screw provided that you first drill a hole with a diameter of 1mm less than the diameter of the screw to a depth of 20mm (until you drill through the tube).

For example : for a screw with a diameter of 4mm, use a 3mm drill bit to drill a hole through the tube.
