good question, i've always thought it was to be sure the sections were fully
mated... you couldn't put in the big bolts unless those holes lined up which
prevented bolting up a partially mated joint.

What is the reason that Rohn uses two differant size bolts on the legs of
the 25G tower ?

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