[GreenKeys] ASR-33 mounting screws

[Chris Elmquist]

Paul,

I sure didn't mean to mislead anyone nor claim that any of my observations
were definitive.

My adventure in trying to find the #6-40 screws, no matter how standard
they once were seemed to reveal that they are no longer as available or
"standard" as #6-32, which you can find at any corner hardware store.

Others have found some sources for #6-40 stainless screws of various
lengths... none of which are the exact match for the #6-40 slotted cap
head screws used everywhere in the machine but they would likely be
suitable replacements in most cases.

I also apologize for hijacking the original thread...  I really only
wanted to comment on what seems to be the rarity of any of these screws
in the model 33's so the suggestion of keeping a "hell box" is really,
really good.
