if they will replace the frame, I'd do that no matter what time of year it is. This is a funky mistake that should not have made it past the manufacturer's q/c inspection.

Green loctite is a stud and bearing mount solution that will only allow removal with the application of heat. Red loctite is a super strong thread locker for use with damaged threads, and Blue loctite is the normal thread locker. If you clean all threaded surfaces thoroughly with acetone before assembly, blue loctite should work fine.

But if it were me, I'd return the frame for a NEW ONE.
