Interesting, John. Sounds plausible but haven't noticed it so
far...certainly if it has occurred it has been less of a problem here than
the previous non-SS hardware breaking when I attempted to back off nuts for
other maintenance or changes on the antennas.
My C51XRNjf and WARC7jf and the top 70' of their tower and associated
Phyllistran guys are scheduled to come down within the next month to make
room for my growing 6M EME array. I'll have a look. (They're for sale,
too...)

What an awesome QTH! I also use stainless steel hardware however I have
seen severe salt spray corrosion to aluminum where the S.S. is in contact.
What do you do to protect the tower system from corrosion?

I live in a salt-air environment and have replaced just about all U-bolts
and
other such hardware with stainless steel. Be sure to coat bolts with an
appropriate compound before installing nuts--if you are not familiar with
this,
ask your SS supplier.
Also, per advice from F12 many years ago, I assembled elements and then
painted
them with XIM400, which has protected them nicely. At some points, I have
had
over 50 F12 elements up at the edge of a cliff with saltwater to the
horizon
and little fluffy balls of salty foam flying up and over.
