Self-Locking Hex Bolt

About this product

The Self-Locking Hex Bolt (#90118WA021), an essential part in both the Body/Deck Board & Deck Trim Cover and Electrical/Windshield Washer systems of Toyota vehicles, plays a crucial role in securing components in place. This fastening hardware, when engaged, locks itself into position, securing the attached parts against vibration-induced loosening. Over time, however, the bolt may wear out, lose its self-locking capability, or become damaged. If this occurs, the bolt's function is compromised, potentially leading to loosened components, system malfunctions, or safety issues. Replacing the Self-Locking Hex Bolt (#90118WA021) with a genuine Toyota part ensures vehicle compatibility and is backed by Toyota's genuine parts warranty. It maintains the effectiveness of the secured systems, therefore contributing to the overall safety and performance of the vehicle. Optimal functioning of the Self-Locking Hex Bolt (#90118WA021) is integral to the smooth operation of these systems.
