Later this year I am going to erect a Rohn 45.  Before I start this job, I
have been checking everything on the ground to be sure all is good.  I
discovered that the bolts that connect the tower sections have been hot
dipped in zinc.  They are very tight, and I think that it might be too
difficult to tighten them on the tower when I am 30 feet or higher.  Should
I take a tap and die to clean out the threads?  Lock washers were not
included.  Should I get some zinc ones before I start this job?


The manufacturer of an outdoor safety-critical structure has included outdoor-rated safety-critical hardware for assembly and you're thinking about replacing it with cheap bolts from the local hardware store that will rust before the first winter is out?

Seems suicidal to me. Please make sure the tower can't fall on anyone else when it does.
