What type of bolt do I need to order?

Hi, I noticed today the front deflector (?) that goes in front of the front tires was hanging low on one side. After investigating, it looks like the bolt that is supposed to hold it on has come loose and fallen out.

Not sure the best way to describe it. But if you go to the front wheel well (either side), there's a couple screw holes that hold the fender to the black plastic splash shield and the rubber wind/rain deflector that hangs down in front of the tire.

Anyone know the part number, or what size bolt/screw to use in its place?

Replying to myself... I think it is 081466162H. Is this something the local dealer would have in stock, or should I just order it?

I suggest calling your dealer and asking. They often have various fasteners in-stock.
