Design Guide 7- Errata, Mistake?

[ToadJones]

On page 48 of DG7 under "crane column cap plates" the author makes mention of using "finger tight bolts with upset threads as a means of reducing bolt fatigue".

Do you think "upset threads" is a mistake and should be "damaged threads"?
I am unaware of upset threaded bolts being used for anything by AISC.

"Upset threads" means the same thing as damaging or burring the threads so that the nut cannot back off.

Common terminology in our environs, too... have seen it referenced as upset, peened, damaged and burred.

I have only seen the term used for bolts that have a root diameter the same as the bolt shank....a significant difference in terminology.

In this case, I think it's pretty clear he means to damage the threads, otherwise why would it be linked with "finger tight"?
