What is this metal object?

NOT the key.......wiseguys.

Seems to be cast steel, weighty. Just found on the warehouse floor here in central Florida. All searches come up with items that are close, but not close enough. No threading inside. No packaging found.

Note to OP and others, if these are important keys you'd do well to not showcase the bidding online. Copying bidding has been done with less than this and most social media can be used to readily trace plenty of IPs and pinpoint someone's location. Just food for thought, keep yourself safe
