I`m kinda fustrated running some EMT this weekend and on most of the male adapters the bushings would not tighten as they should.And yes I tightened the lock nut tight.Any one else share this situation.Can you use the metal bushings w the insulator without the locknut?I might look for some thin locknuts.Everytime I pull on the wire the bushing falls off.Just one of those days.The brand of adapters was Keer 3/4"male adapters.
