[Elecraft] [K3] Case screws rusting

[K9ZTV]

Not being a metallurgist I have no business posting on this subject, 
other than in recalling past experiences with dissimilar metals.

I specifically remember a stainless steel ball-mount quickly digesting 
an aluminum bumper in the presence of everyday moisture and air.

For the price of a few screws from Elecraft (minimal if anything), 
spending research effort on a few rusty screws seems to me a substantial 
waste of everyone's time.
