George et al. --
YES, hardware stores can have SAE grade 5 bolts but NO they are not
the fine thread variety that Rohn (that's R-o-h-n) specifies. I haven't been
able to find them off-the-shelf even in nut and bolt stores here is
Washington State. And watch out, since many hardware store varieties are
cadmium plated or some other "non-suitable" for outdoor use finish.

Subject: Rohn tower bolts
Genuine Rohn tower bolts are hot-dip galvanized, and are the only ones
that won't rust in outdoor service. When I've substituted plated
Grade 5 bolts (available locally in both coarse and fine thread -
don't mix 'em or you'll go nuts trying to dig the right nuts out of
your tower bucket) they rust through the plating in a year or two.
Since tower erection has so many other long-lead items, it makes sense
to stock on hot-dip galvanized bolts and nuts from Rohn or an
intermediate source (K7LXC?). Cutting corners on towers is like
cutting corners on a race car or airframe - don't do it!
