Don't use just two screws. My bike developed terrible vibration at some speeds/revs and it was traced to a fenda extenda that had come unglued and was flapping about in the airstream. That in turn caused vibes to run up the bars. There was only one screw either side holding it on and the glue in the middle had let go.
I put in another two screws to secure it but they were'nt 10mm long, more like 5mm. I worried that with tyre flex the tip of a longer screw might catch the tyre, and at 10mm the point could be felt protruding.
