Just wanted to clear up what is in a standard tower leg bolt kit from Rohn.
and six nuts. That is all. No washers and no PAL nuts. At least this is the
20G, 25G, 45G, and 55G.
I can't imagine that you could squeeze a leg hard enough to create enough
take all the downward force, especially on the bottom section of a tall tower.
to believe the bolts support a good deal of the downward force in shear. I do
that squeezing the tower leg prevents the need for a lock washer, however. I
never heard of nuts falling off of tower leg bolts or a tower leg bolt actually
breaking and/or falling out.
