I was cleaning the chain and noticed these exposed threads near the front sprocket. Is a nut missing here?

That appears to be bolted from the other side, so that bracket is the threaded receiver.

Edit: Confirmed, long bolt from the other side, through the engine case, threading into that subframe bracket, no missing nut.
