It matters whether you are buying 25JBKs or 45JBKs. The ones for 45G are galvanized. This has been the status on these bolts for at least the past 2 years. Seems it was the same back in the mid-70s

I think they are fine thread to keep as much of the basic bolt materail available for shear strength. Fine threads remove less material. I nt eh Rohn towers the threaded portion of the bolt is in she

Sorry for the typos - it is getting late after the club meeting: In the Rohn towers the threaded portion of the bolt is in shear loading so more cross sectional area means a stronger bolt and joint.
