Obviously none of the respondents have had to mate two obstinate
sections of Rohn 25g together.

The smaller hole is for a drift to force the sections into alignment so
the larger bolt can be installed. Then you have an empty hole just right
for a smaller bolt. I suppose it adds a little strength to the joint,
but not much.
