[TowerTalk] ROHN TOWER BOLTS UPDATE

[Drax Felton]

Why even need one bolt?  Just during assembly?    Once the tower is guyed the downward weight holds it together.  When is there an upward force to seperate the sections?

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.
