Ambient Temp Sensor screw size

Hello,
First time poster, newish vfr owner (since October '23). I see my ambient temp sensor is dangling and the little screw is missing. I'm looking in the manual and don't see it's size or type. #16 in this diagram screenshot I've included. Surely I can get this at a local hardware store, anyone know the kind of screw I'm looking for?
Thanks in advance for your help. I've still yet to go to the introductions section and post a pic of my bike but its in a state of transition while I pull things off and "fix" them. This being one of those.

 

Usually those are a small self-tapping screw. On my 1300 it is about 12mm long as it only has to pass through the collar on the sensor and then into the hole in the fairing.

 

Partzilla also shows it as a M4 x 12mm Tap Screw and looks like this. Should be able to get them at any kind of hardware store.

 

awesome, thanks for the help fellas
