[TowerTalk] ROHN TOWER BOLTS

[Mark Pride via TowerTalk]

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.

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?
