The US Tower anchor bolts are one-inch diameter steel "J" bolts, with about
a 6-inch horizontal segment at the bottom. Frankly, I can think of few
things more fundamental to the strength of a tower than its anchor bolts.
To try to save $12 per anchor in the face of the major investment you're
making would seem foolish economy.
If you're erecting the tower under a building permit, I doubt the permit
authority will allow you to substitute the bolts, anyway. If you aren't
erecting it under a building permit, . . . Well, that's a different
thread. :)
