They're a metric sheet metal screw. Aside from just buying some new ones from Toyota or getting them from a Toyota in a salvage yard the closest I could find locally was a #10 sheet metal screw (It was #10 or #8... it's a bit larger though and will open the hole more but it works fin and they're easy to get.
