How many bolts? Obviously 10 bolts will have 10x the strength of one,
including pull out strength.
Most SS towers are designed for fewer large bolts rather than many small
bolts. Part of the reason for that is corrosion concern.
Let the flange hole size be your guide! Of course, take a quick glance
at the manufacturer's foundation plans...

Dear towertalkers,
The are claims in a discussion on Face Book that an anchor bolt, "5/8 in. x 12 in.
Hot-Galvanized", is suitable for a free standing tower. Someone even claims it is
used for a 400' freestanding tower. It doesn't make sense to me but I might be overly
pessimistic.
I hate to start lengthy discussions and this might be one of them so, please,
comment only if you have a well grounded answer. I'm sure there are plenty of
opinions about it like my own, but I would like to know if my guts feeling is
right or wrong. What I am afraid of is that you can pull out an anchor bolt
like that right out of curred concrete.
