[GreenKeys] Weird hardware size

[Bruce Gentry]

One thought that comes to mind is that a finer thread might be more 
resistant to loosening under vibration and impact loads. A fine thread 
on  high strength alloy hardware tends to be able to withstand higher 
tightening torques and loading. As for lampshade hardware, appliance 
manufacturers were and are notorious for deliberately creating and using 
odd hardware to force the owner to obtain it only from their "Local 
factory authorized and certifer dealer and service center".
