Is this a part of my van?!

[MLR]

Hi all
I've just installed some rear speakers in my T6. Whilst I was putting the glovebox and a-pillar trim back I heard a rattle and this dropped on the floor. Looking at the end it seems to have been cut so I'm not convinced it was a part of the van. Anyone recognise what it might be from please?
Thanks
Mike

Looks like a rivnut

having done the same job as yourself I haven't come across that part. Usually T15- 20 black head screws in that area

Thanks. It didn't look like any of the fixings I found during the job so I'm guessing it's something that might have been dropped by the converter during the conversion to a camper.
