Passenger Side Under Dash Fixing

[WIL35]

Can anyone tell me what type of screw or bolt attaches the piece of trim above the passenger's legs, next to the footwell vent? My one is hanging down and I don't want to pull the whole thing out to see what type of thread I need to hold it up.

It goes through the hole shown below.




I know it's a minor point, but I would like to have it correctly positioned, as at the moment it is halfway across the vent.

Thanks!

Excellent, thanks all. I shall have a rummage with a self tapper.
