I've used DX Engineering's 2 1/2" SS U bolts on my KT36XA mast bracket and
they DON'T hold.
You can't tighten them enough without galling. I visited DX Engineering
while at Dayton this year and expressed my displeasure with their 5/16" vs
3/8" SS U-Bolts and they just shrugged.
I'm also looking for 2 1/2" x 3/8" SS or Galvanized U-Bolt source.

Subject: [TowerTalk] SS "U" bolts
I am currently building several antennas which will be installed in a
corrosive environment and I'm looking for bolts to clamp the boom to the
mast. DX Engineering sells SS "U" bolts along with an aluminum saddle. I
normally use 4 mast and 4 boom clamps when using 3/8 dia steel "U" bolts,
however DX Engineering seems to recommend 8 boom and 5 mast clamps when
using their 5/16 dia "U" bolts. I believe that stainless steel has less
tensile strength than steel and also using a reduced diameter concerns me.
Are there any better sources SS "U" bolts that fit 2 1/2" and 3" O.D.
tubing. I'd also like to hear comments from anyone using the DX Engineering
bolts.
73,
John
