First, start by checking the length of the screw. Skinbased skis only accept 23 mm screws. Mounting holes in the ski are drilled by robot, ensuring that they are drilled in exactly the correct location and to the correct depth. At the factory, during the installation phase, screws are placed in all the ski’s screw holes. To finish tightening, use a PZ3 screwdriver. Installing the screw may require some force or pressure. If the hole in the ski does not seem to line up exactly with that in the binding flex plate, slightly loosen the rear screws and realign the flex plate.
