At least it's not some assembly line guy's half eaten lunch stuffed under the carpet. Or the socket that was left behind the rear seat that rolled around for a few months.I would chalk it up to left over assembly trash of some sort.

Unless it has a valid part number to reference, I would not put too much thought into it.
