This is a plastic screw which you can screw right into the wall after drilling a hole. These were designed for the Multiboard system specifically and they fit very well.

Please note these are semi-permanent screws in the sense that you may not be able to unscrew them out of the wall; if you need to remove them you may need to pull them out with pliers.

These are much weaker than anchors + metal screws, but they get the job done with a reasonable amount of security at a very low cost.
