Gary,
If I were you, instead of fighting it, I would buy galvanized (tapped oversize)
hex nuts and use them instead of the locknuts. I don't know when they started
using locknuts, but for decades they did not use them. There are thousands of
towers installed without locknuts and without problems as a result.
