Hi Peter!
The Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C46DR uses M12 hex head cap screws. The grade isn't listed anywhere, but I would use at least grade 5. It's also an M12 conical toothed washer if you need that as well.
Also just in case, this will fit the following vehicles:
2022 to 2027 Nissan Pathfinder
2022 to 2027 Infiniti QX60
You are probably aware of that, but still figured I would mention it. : )
Where you mid install when you noticed the original bolt/screw was missing?
