help stripped air box bolt

[Caesar]

Like many I needed to charge by battery for the riding season so I took it out and charge it. When putting everything back I noticed that I was missing one of the bolts that secures the plastic mount that goes over the battery and the air box. So I take the only one that I can find and notice that its threads are stripped.

Now I'm starting think that someone is punking me. So now I am worried about not having any bolts to secure the air box. Does anyone know where I can go to get a new set of bolts? do I have to order them from Yamaha?
