Stuck Nut on the elevation bolt on C-band big dish

[Hockeynut]

I would not worry to much about it...Go with what cham mentioned...Galvanized or even Stainless but once you have everything adjusted it does not much matter...Throw some Pb Blaster or Kroil on there every 6 months and you wont have that problem again.

Even better, put some anti-sieze compound on your bolts when you assemble. It works.
