[GreenKeys] teletype...Whhhyyy?!

So that makes sense. But for non-critical, non-thin situations, why not use something more common? These standoffs for the rear terminal strips are certainly non-critical. No biggie. Just very interesting to ponder the decisions made at such a large corporation with some very complex mechanical wizardry at foot. I also would guess that maintaining inventory for more than one thread if not necessary would be an added cost.

Teletype normally used the fine-thread standard hardware such as 6-40, 8-36, 10-32.  Better quality.  If you are building precision machinery you want more threads per inch, especially if you are screwing into fairly thin metal.
