Can anyone identify where this may have came from?

Can anyone identify where this may have came from? I found it in my driveway this afternoon and assume it must have came from my 2017 Tundra or the wife’s 2018 4 Runner. I know it’s a long shot but figured I would ask the gurus!

 

This looks like one of the bolts that hold your Tundra bumper in position.

 

The only mod was a 4” lift kit about 4000 miles ago and I had the re torque done after 500 miles. I will check bumper tomorrow and all the lift components. Thanks.

 

I don't know, but those kinds of flanged nuts are indeed very common on vehicles and not so much anywhere else so it likely is from a car rather than just some random hardware from a bookshelf or something.

 

I second the bumper mount nut.

 

Got anything for scale in that photo? A quarter or something would be helpful.

 

Flanged nuts I can name a few: Leaf spring forward and rear mounts, U bolts, and rear shock bottom nut. Hope that helps and good luck, better to look over everything and retorque while you are checking around the chassis

 

The bottom shock mount nut is flanged like that too.

 

I have crawled all under the truck and see several similar bolts. I can’t see where any are missing however. I guess I will just drive until something falls off. Thanks for all the input!

 

I’d up my car insurance amounts

 

It's a nut, not a bolt.
Those are used un a few locations that I can think of. Definitely lower shock mounts and maybe bumpers or sway bars.

 

Amazon Prime Mercedes sprinter van been in your driveway recently?

 

Do you have a TRD pro skid installed? That’s the same flange nut that goes to the two most rear bolts. The ones that go through the crossmember.

 

No TRD skid plate. I will be back under there tomorrow installing Budget SS exhaust from the group buy and will look around again.

 

check rear shocks if any missing
