Product Description
The genuine Nissan 01225-00131 flanged lock nut is a high-grade, high-strength fastener engineered for stable, vibration-resistant fastening of structural and suspension components. The integrated flange design increases the load-bearing surface area, effectively distributing clamping pressure over the fastened part and eliminating the need for an independent washer. The self-locking function prevents accidental loosening caused by continuous vibration and dynamic loads generated by the drivetrain and uneven road surfaces.

Maintenance and Installation Notes
Due to their prevailing-torque design, self-locking nuts provide maximum locking retention upon initial torque-down. Reused self-locking fasteners lose their nominal friction and locking efficiency, which can result in unexpected backing-off and significant safety risks. Common failure symptoms include thread deformation, bolt stretching, corrosion-induced seizing, or loss of specified clamping preload. Whenever suspension or drivetrain assemblies are serviced, replacement of flanged lock nuts is strictly recommended in accordance with OEM service procedures, adhering strictly to the manufacturer-specified tightening torque.
