EdgeTech

So I changed out my spark plugs in my 2011 Edge Sport 3.7l AWD. That went well actually except for me dropping and losing a bolt for some kinda support bracket thats under and behind the Throttle body. Theres only 1 bolt that goes back in there and I lost it. Does anyone know the specs of that bolt so I can replace it, or where to find a replacement?? Im not above going to the hardware store and getting a close match since its not going anywhere crucial like holding down the manifold.
