What should be done if a fiber or nylon insert-type, self-locking nut can be threaded on a bolt or stud with only the fingers?

Reused
Tightened with a wrench
Rejected
Lubricated

The correct answer is: Rejected

If a fiber or nylon insert-type, self-locking nut can be threaded onto a bolt or stud with only the fingers, it indicates that the nut has lost its self-locking ability due to being previously used or damaged. Choosing to reuse such a nut would compromise the integrity of the fastening system, as it may not provide the required locking torque, potentially leading to loosening during operation. In aviation maintenance, safety and reliability are paramount; therefore, the correct course of action is to reject and replace the nut rather than reusing it.
