I have taken to lubricating new stainless steel nuts/bolts before
putting them together for the first time, especially in the larger
diameters greater than say 1/4". Why? Because it is darned inconvenient
to have one of them gall and prevent their being tightened into position
the first time. I don't know if this is a common problem but I don't
want to find out as it is most inconvenient to have a 1/2 inch or so
diameter SS bolt and nut gall badly when first assembling them and
thereby prevent squeezing the parts together properly for which the
bolts were employed. A good anti-seize product such as Never-Seez or
similar is a good choice to put on the threads before assembling.
Symptoms of the problem: You are tightening the nut on the bolt and
before reaching significant clamping force between the parts being
bolted together the nut gets really hard to turn potentially fooling you
into thinking you have bottomed out and are clamping the parts together
although this is NOT the Case. So you start to back the nut off thinking
maybe you can lube it and all will be OK. Not so pilgrim, trying to
back the nut off brings more galling., I hope you have means of
removing the ruined nut and bolt without damage to the parts being
bolted together. The only way to remove the bolt with sockets or
wrenches is to literally twist the bolt in two. If you have access and
a plasma cutter or cutting torch you might be able to do the job and
avoid hurting the parts. A SawzAll (reciprocating saw) with the right
blade and maybe a spare blade might be a good choice. However you do it
you are out significant time and effort and a nut and bolt. I have had
this happen a couple times and with luck and a good anti-seize product,
never again.
Oil, WD-40 etc may let you assemble SS nuts and bolts without galling
(maybe) but much later when these options are long gone from the threads
you may very much regret not using a good anti-seize which will outlast
silicon spray, WD-40, etc. by a great margin.

Just my 2 pennies here, but I'm going to be using SS hardware but I'll
be using SS Nyloc Nuts. Also if using SS, be sure to use never seize
compound, if you don't, the nuts will almost for sure seize up if you
try to remove at a latter date. Lesson "hard learned" with SS bumper
bolts on my Hot Rod!!!

Heard a story many years ago about a tower that was installed in KH6
with stainless steel hardware and after time, with the constant trade
winds, the nuts all fell off.
There is vibration to contend with in certain places around the

One other point on the tower hardware from Rohn these days. They
have changed their hardware where the nuts are designed to be put on
the bolt ONE time. To remove the nut, one will damage the thread of
the bolt (sorry - forgot the description of this design - lock
nut?). Guess the concept is, you put up a tower one time and never
take it down! However to their point, it prevents nuts from backing
off (good thing).
Regarding the new hardware you find in the tower leg of the new
material - you might want to change it. The current nut design has 3
indentations on the surface - pretty easy to spot. Bolts are fine,
just need to change the nuts.

Larry is correct in that both the 25 and 45 use different size
bolts and if
my memory serves me, this would be 4 different sizes in the case of
these
two tower types. I have never seen washers used with these. It is
noteworthy, that should you be putting tower sections up, to be
ABSOLUTELY
sure that the legs are clear inside. Run a garden hose through the
leg to be
sure there is no blockage, or even push a ground rod through each one
for
example. I can't tell you how many times I have found blockage in the
legs...dirt, mud, bugs, etc. And while on the subject, occasionally
found
that the blockage was TOWER BOLTS that were packed in the legs by the
manufacturer which had never been found/removed. -Mike

25G and 45G use two different sizes at each joint on each leg. I
forget what
size they are offhand. DX Engineering sells leg bolts and their web
site may
tell you what the sizes are or the perhaps the Rohn web site.

Subject: [TowerTalk] ROHN TOWER BOLTS
There is quite a debate at one of our local Saturday morning breakfasts
gabfests about Rohn Tower Bolts.
Some say that Rohn uses two different size bolt sets for each tower
section.
Some say that Rohn uses only one size bolt-washer-nut sets for all
towers.
So what are the facts?
Are there different size bolt sets for Rohn towers, and are they
different
depending on the tower ? 25G, 45G and 55G?
