I'm trying to figure out the thread pitch for the knob of an airplane's altimeter. I thought it might be 4-40, but it's finer than that. That's the finest standard pitch I can measure. I checked with my metric gage and .5mm looks like a pretty close match (although I'd be surprised if it's metric, but who knows?). The shaft diameter is about .113".
Any ideas what thread this might be?
Thanks,
Jay
