As far as I can find the thread on the studs on the Smiths/Jaeger is 3BA however, I have several nuts (these are the round ones with various sorts of knurling on the periphery) that seem to have a different thread and will only go onto most of the instruments a turn or 2 before jamming. Does anyone know if there is more than one thread used for these studs and other then 3BA what is the other thread.
