Hi Bill,
> Oddly, the 3300 pF use 10-32 screws and the 470 pF use metric.
Not really. The 3300pF also has metric threads, but larger than those of
the 470pF one. These are M5 threads: 5mm nominal diameter, 0.8mm pitch,
60 degrees. It just happens that the 10-32 screw can be screwed into
that thread, because its pitch is almost exactly the same: 0.79375mm,
and it is sufficiently thinner (4.6mm) to accomodate the difference in
angle (55 degrees). But it is a poor fit, and the screw might work
itself loose. So, it's better if you use the correct metric M5 screw
with these caps.
Manfred.
