These are called "expanding rivets". There are many types and sizes for our cars. There's one that I found that looks like the one that rsutoratosu shared pictures of. See PN #51168197908. I'm not entirely sure if this is the size you need but ECS Tuning describes it as "Used to mount trim and other various components". I checked RealOEM and couldn't find the specific application for it.
