I asked UST  how much Torque should be used on both the 12 x  1.125 inch anchor 
rods....and also the 18 x  1 inch leg bolts.
I also told em I used never seize on both anchor rods and legs bolts.  Also 
told em the anchor rods are 104 ksi yield strength..and 
came from portland bolt...and are 60 inchs long each.... with 6 inch threads on 
each end.   Told em that the 18 x leg bolts are 
A325 bolts and are 3 inchs long each.    Everything has heavy duty flat washers 
and slightly oversized nuts on em. 

Their reply was...... snug fit !    This is for my UST  HDX-689 tower.  This is 
the old style 689..that weighs 5000 lbs..without the ants and mast, but that
weight includes the bearings  and small  PP  rotor.   The crane operator 
weighed the tower when it was unloaded. 

What is  ..snug fit ?     Trying to get  answers from UST at times can be 
exasperating. 
Does anybody even know ?    I was thinking  perhaps  125 ft lbs for the anchor 
rods......and 100 ft lbs for the leg bolts.   Leg bolts can always be 
replaced...
anchor rods cant. 

Tnx...  Jim   VE7RF
