The bolts should be listed on the "Tower Engineering Sheets" AKA
"Structural Analysis Sheets." Tower Typical Standards are bolts
designated as ASTM A325 which corresponds to Grade 5, while ASTM A490
corresponds to Grade 8.
I hope that helps.

I am not sure what a Rohn anchor bolt is, usually the tower either sits
on
top of the concrete with a pier pin or a tower section is embedded in
the
concrete. FWIW, most structural bolts are hot dipped A325.
