It's not the rails that are tapped, it's a captive strip. Think
of it as a 84-uple captive nut.

Discrete captive nuts are useful when you have oddball panels
like those from Analogue Systems where the holes are k x .2"
from the edges instead of the standard .1" + k x 2". Otherwise,
tapped strips are so much better.

I think captive nuts are a relic from the times when factories
weren't tooled to produce tapped strips cheaply like they are
now. Just for fun, I'd like to see a _Comment c'est fait_/_How
it's made_ report on a Schroff factory...
