[GreenKeys] 6-40 UNF and other wierd screw sizes

[jhaynes@alumni.uark.edu]

Teletype mostly made their own.  I haven't tried locally, but have you
looked at a company that specializes in screws?  I've bought other odd
sizes from such a supplier.  In the yellow pages here they are under
Bolts & Screws, and also under Fasteners.

(turning on the philosophy mode) One could argue that Teletype's great
manufacturing capability was both a strength and a weakness.  There was
nothing to inhibit a designer from designing a new screw slightly
different from anything in the book instead of figuring out how to make
do with a size that was already being manufactured.  So there were a huge
number of part numbers occupied by screws and nuts and washers.
