Keep looking around the engines you will find where it came from. I had one like that come loose and it held a bracket to the side of the engine.

It looks like it only had about an 1/8th of the threads screwed into whatever it came out of so its something wide that it went through.

Mine was up top by the air cleaners, to the left in the middle holding a bracket

Is the head of the bolt a 14mm or 12mm?

Looks like it's pretty beefy with course threads. Is it possible that's an engine mounting bolt? Check all four feet on each motor to make sure.

@Milwarc mention engine mounts...double check all your mounts. Looks like the bolt under the air case too, but that one would not have come out of the airbox I wouldn't think. Best of Luck!

As large as it is, i would guess engine mount also.
The imprint on the washer should lead you in the right direction

My first thought was also the top of one of the motor mounts
