What size nut for heater control arms

[Ronin]

Hi

Does anyone know what size (Including thread pitch) nuts I need to attach the heater/fresh air control arms onto the threaded studs within the dash as my van came without them fitted and i need to fit them properly now and after a long search through my tool boxes I don't have anything usable, it's quite a tight pitch on the stud (almost machine screw pitch).

Thanks
