[TowerTalk] [Bulk] Rhn 45 bolts

[Grant Saviers]

"they are very tight" -  does that means nuts to bolts or bolts to 
holes?  If nuts, I wonder if you are using HDG nuts with the HDG bolts?  
The correct nuts are oversize tapped and should easily go on a HDG 
bolt.  Usually, they are tapped after galvanizing so the threads are 
bare steel.  If bolts are too tight to holes, then cleanup the hole Zn 
flash with a drill bit or better yet a bridge or tapered reamer if you 
can find one the right size.  Split lockwashers have a marginal benefit, 
Nordlocks are far superior, but I don't think Rohn has even split ones 
in their bolt kits.  You should use the Rohn bolts since regular small 
diameter HDG bolts are likely less than grade 5.  For 1/2" diameter and 
larger A325 structural grade bolts are available HDG.
