I'm not sure what the other nuts are, but they weren't the standard 1/2" nut. The threaded rod would only go part way into the nut, not the entire way through. I explained that to Torklift's customer service guy.
Sounds like by description you weren't 'shorted' or given wrong nuts but the 3 fastguns were supplied with different style of lock nut. Why a difference in supplied nuts unknown but if 'Deformed thread' style lock nuts- they do by design require more effort to install. They are more positive (IMO) and semi-permanent than a nylon lock nut. However they really don't serve a purpose on the fastguns as far as function, other than as stated a backup if the threading nut stripped/broke.
I'm not replacing mine but if I had my rathers my fastguns would all have been supplied with the upset thread lock nuts. In your case I would have replaced the 1 nylock with deformed thread nut. Doesn't help with your original frustration during assembly but for the next guy trying to figure out 'what the heck'...
