NISSAN 08918-6401A Self-Locking Flange Nut

The genuine Nissan 08918-6401A part is a high-quality self-locking flange nut (NUT-SLOCK) manufactured to strict factory specifications. The integrated bearing flange functions to increase the contact area, provide uniform surface load distribution, and eliminate the need for a separate washer. The self-locking design prevents unintentional loosening caused by vibrations, dynamic mechanical loads, and thermal expansion cycles in critical suspension, drivetrain, or subframe fastening applications.
