I knew a fellow one time who put together a nice little

nickel-cadmium plated screws.

Nickel-cadmium usually refers to the metals used in fabricating a
family of secondary cells used in redchargeable batteries, while
cadmium, by itself, was once used to plate mechanical fasteners.

Just one more inconsistency in his postings. I didn't even mention
the nickel component
in his alleged plating because it, like gold, has a vapor pressure of
about 10^-11 torr at around 800 degrees, and thus won't boil at 20
degrees even in interstellar space.

But I think you're right. I've never heard of Nickel-cadmium plating
of screws, but I
used to use cad plated hardware all the time.

It
has dropped out of favor and its use may now be prohibited for that
purpose due to its toxicity and effect on the environment.




Yea, I'd have to call BS on that one...
