Unidentified fastener

I found this on my passenger seat after an oil change. Dealer wants me to bring it in to identify, but I’m not sure it’s worth a trip. Has anyone seen one of these in their truck? Thanks!

 

No, i've never seen something like that in any Toyota truck.

 

Thanks. It doesn’t look like any of their clips or fasteners that I’m accustomed to seeing. Thinking someone dropped it while doing the service.

 

Looks like something to hold the carpet or interior paneling down, though I haven't seen that specific one on anything before.

 

Almost looks like a fastener for floor liners

 

Rear under seat storage hold down?

 

Good ideas. I have the Eagle Klaw floor mat clips, so that’s not a floor liner clip. No under seat storage in my crew max. If something falls apart, then I’ll know that’s where it goes, ha.

 

Is there a part number on the bottom side where the threaded stud is?

 

No part number unfortunately.

 

Have no idea. The theory of it being dropped by someone sounds like an accurate one.

 

That is a thumbscrew to hold an accessory attached to a bracket. Check your jack mount, might be a rubber strap there, can't recall. Most likely for aftermarket accessory though.
