Under vibration conditions, which anti-loosening method is better for standard fasteners: spring washers, lock washers or thread adhesives?

Spring washers (GB/T 93): Elastic preload, general light vibration, low cost. Lock washers (internal/external teeth, GB/T 861/862): Teeth embedment, stronger anti-loosening, suitable for medium to high strength. Thread adhesives (anaerobic adhesives): Permanent/semi-permanent locking, sealing and rust prevention, suitable for critical connections that are not frequently disassembled.
