I found this on the ground while camping at a campsite (in Utah).

Measurements:

• 45mm long
• 23mm wide
• 13mm thick
• 7mm – inside diameter of smaller hole (not threaded)
• 11mm – inside diameter of larger hole (threaded; through hole)
• Heavy – solid steel
• Black powder coat.

What's interesting is the smaller hole does not go all the way through the part. So I'm guessing the purpose of it is that some kind of locking pin fits into it to keep this from coming loose while traveling.
