[ARC5] [GreenKeys] Source for #2-64 cheesehead screws?

[Jim Haynes]

You remind me of a funny story.  I used to have a friend with a watch
repair shop.  His workbench was right in the store, so customers
could see him working (and he could see them come in).  He told me
about two people who came in once and were watching him intently as
he worked on a watch.

#1: "How do they make screws that tiny?"

#2: "They don't make them.  They come ready-made."
