TOYOTA 90189-T0003 Screw Grommet

The genuine OEM Toyota 90189-T0003 screw grommet (factory designation: Grommet, Screw) is a premium-grade, durable fastener engineered for secure and vibration-free mounting of various vehicle body and interior components.

Key Features and Functions:

• Vibration Damping and Protection: Prevents direct contact between metal screws and body sheet metal, reducing vibrations and minimizing the risk of galvanic corrosion.
• Secure Fastening: Provides a stable threaded receiving surface in areas (such as thin sheet metal or plastic panels) where direct screw retention would not hold properly or could easily strip.
• Superior Material Quality: Manufactured from high-grade, automotive-grade plastic (typically polyamide or POM) that resists temperature fluctuations, under-hood chemicals, and aging.

When is Replacement Necessary?

Over time, plastic fastener grommets can dry out, become brittle, and break due to temperature cycling and environmental exposure. The most common symptoms include rattling or loosened panels, or physical breakage of the grommet during service procedures (such as removing a bumper cover or wheel arch liner). To ensure a perfect fit and rattle-free operation, it is recommended to replace loose or damaged grommets with new genuine OEM parts.
