What is the reason that Rohn uses two differant size bolts on the legs of

I am sure there is a good one or they would not have done that.

Probably only the engineer at Rohn would know.

It may not be as a safety feature when mating, because Rohn 55 uses
two bolts exactly the same size in each leg. Most likely it is a stress
rating issue, and that's all the bolt size needed to do the job.
