Default Does anyone know what this mystery bolt is?

While checking out under my '04 4Runner, I noticed this brass hex bolt in the cross member. I'm pretty sure the fluid around it was from either leaking valve covers at the gaskets, or possibly lube from when I lubed the drive shafts.

Anyways, what is this bolt for? It looks like a "fluids" bolt, but my transmission is sealed, and it's not diff or T/C case. Seems to be the only one like it.

That does indeed seem to be "Front Differential Mount Nut No.1"

Thanks for taking the time to answer this, I had googled and couldn't find anything. Not sure why they used a bolt that appears so different, unless maybe that mount has a bushing of some sort within it?
