Jim's thoughts are the same as mine. Has anyone here purchased new tower
sections & if so, what size hardware did it come with? I suspect that
the larger hole is for alignment.

The smaller bolt is then inserted in it's hole and tightened. The small bolt then holds the assembly in correct alignment for the large and necessary bolt to be inserted and be torqued to specification.
