Uhm...there are a few scratches on the plexiglass ...
The letters and numbers on the screw head indicate the material, i believe it is polished stainless steel.

Go to your local hardware store or bicycle store and buy a good quality metric set. Buy quality tools that will last because they'll come in handy again one day.
Yes ... also because scooter manufacturers only use the metric system; remember not to tighten the screw too much on the plastic otherwise it could crack (the plastic, not the screw).
