[TowerTalk] ROHN TOWER BOLTS

[john at iguanavilla.com]

What is wrong with the standard Rohn hardware?  I had a Rohn 55g tower in
Aruba 1/3 mile from the sea.  Corrosion was a huge problem.  Big grips
lasted only three or four years, the tower was painted multiple times a year
and still developed holes.  When I took it down after a decade the original
tower hardware was in excellent shape.

NO FLAMES HERE!

Here is what I have for choices:

Not the average Home Depot / Lowes "Stuff"


A286 Super Alloy-With approximately 26% nickel and 15% chrome, this
iron-based super alloy brings you the strength of alloy steel with corrosion
resistance similar to 18-8 stainless steel. It meets ASTM A453 Grade 660 and
is not magnetic. Screws have a minimum Rockwell hardness of C31 and minimum
tensile strength of 140,000 psi.

17-4 PH Stainless Steel Alloy-Combines the high strength of alloy steel with
the corrosion resistance of stainless steel. It meets ASTM F593 Grade 630
and is magnetic. Screws have a minimum Rockwell hardness of C31 and minimum
tensile strength of 140,000 psi.

Alloy 20 Stainless Steel-Also known as Carpenter 20 screws. With excellent
resistance to sulfuric acid, these screws have a minimum tensile strength of
80,000 psi.

I also have a choice of 18-8 or 316 SS Nylon lock nuts.
