I have owned several Universal Towers and have never seen this egging
condition. Perhaps it depends on the size of the sections, I always used
the larger ones. The OEM bolts will quickly corroded into nothing and
after seeing this once I never used them again. I had one 50' tower in
Aruba with stacked 10m and 15m monobanders. The wind never stops in Aruba
and there was constant force and movement on the tower and antennas. There
was never any egging and in fact do to the salt spray and the upsidedown
design the sections were severely locked together when I removed it.

I saw plenty of Heights and Universal towers that were egged out
during my time on Ohio. Many of them had the bolts/nuts tightened
to the point that the legs were somewhat flattened but that did
not prevent "egging out". I know one old timer in the Columbus
area who replaced towers twice within 10 years - both times because
they were so badly egged out that nobody would climb them to repair
antennas.
Again after what I saw of those towers, I would not trust one here
in the higher/constant winds in Florida. If I had to use a free-
standing tower here, it would be the biggest sections available
from AN Wireless or a properly engineered commercial - Rohn SSV,
Pirod (if they're still around), etc. - tower with bolted flanges.
