Hi Howard,
Yes, they are probably "strong enough".  But maybe it's a good time to
remind people on the reflector that all stainless alloys are weaker than
similar-sized hardware of "normal" carbon steel like Grade 5 nuts and bolts,
or guy wires.  In the case of a major tower installation where a building
permit is obtained, and the structure is to be covered by insurance, I would
be reluctant to use any leg-bolt hardware which does not meet the tensile-
or shear-strength requirements stated by the tower manufacturer.  If there
is a catastrophe, a sharp-eyed insurance adjuster MIGHT just notice the SS
bolts deviating from original specs and cause you lots of grief, even if we
know that the bolts might not have anything to do with the failure mode.
