Self-Locking Collar Nut

About this product

The Self-Locking Collar Nut (#90118WA259), an integral auto part in the Drive-Chassis/Rear Spring & Shock Absorber and Drive-Chassis/Rear Axle Housing & Differential systems of Toyota vehicles, plays a pivotal role in securing components together while in operation. This part employs a special locking mechanism that grips the bolt threads when tightened, providing a secure and solid connection that withstands vibrations and movement. However, like many mechanical parts, the Self-Locking Collar Nut (#90118WA259) can wear out over time, losing its ability to grip effectively. This may result in loose connections that could potentially compromise the performance and safety of the vehicle. Therefore, periodic replacement with a genuine Toyota part is highly recommended. Genuine parts not only offer precise compatibility with your vehicle but also bring the assurance of Toyota's genuine parts warranty. By using a Self-Locking Collar Nut (#90118WA259), the overall operational efficiency and safety of the system are significantly improved.
