It would need to be the same diameter of the rivet. If its to be fixed to plastic when I would be very hesitant in using rivets as the pressure of the compressed rivet may fracture the plastic. I'd be incline to use nyloc nuts and bolts (stainless steel) with large diameter flat washer/s. Would also make removal easier as well.
