Many bike side covers have those pins going into the rubber grommets, but they tend to brake off the plastic overtime.
Those ones are a close replica of the Honda Goldwing's pins, but may work on other bikes as well (I've been told they are quite similar).
Just sand both sides and use some epoxy!
Designed from: Honda Goldwing 1994 (production range 1988-2000)
