Good point. I don't know about the hermeticity of a screw, sounds
questionable. It's possible the designers were kidding themselves.
I know that I debunked a lot of their theories about what is or is
not hermetic. For example, "hermetic" epoxy isn't. Possibly there
is a Viton O ring around the screw. I think that might be hermetic.
