[TowerTalk] Rohn 65G Flang Bolt Torque Specs

[Grant Saviers]

Portland Bolt has the specs on their web site for tightening A325s. 
However, the question will remain if the connections are "slip 
critical".  If so then the torque is near to the web site value than 
otherwise, which are "snug tight plus 1/2 turn or similar".  Best to get 
the Rohn spec torque value particularly if you have flanged connections 
subject to the cyclical compression-tension loading of tower legs.
