NISSAN 66820-01J00 Screw Grommet

This genuine NISSAN screw grommet (OEM part number: 66820-01J00) is a premium-quality fastener specifically designed for the secure, vibration-free mounting of various vehicle structural components, trim, and panels. This genuine OEM part ensures precise fitment and long service life.

Function and Importance

The primary function of the screw grommet is to provide a secure receiving anchor for mounting screws in areas where thin sheet metal or plastic components alone would not support a stable threaded connection. It prevents screws from backing out due to vehicle vibrations and distributes clamping pressure across the fastening point, preventing cracking of the secured plastic panels.

Signs of Wear and Failure

Plastic fasteners can degrade and become brittle over time due to temperature fluctuations and UV exposure. The most common signs of failure include:

• Physical breakage or cracking of the grommet during removal or from external impacts.
• Stripped or expanded internal receiving bore, preventing the screw from holding tightly.
• Rattling, loose trim and panels caused by weakened mounting points.

To ensure secure and rattle-free mounting, it is always recommended to replace damaged or aged fasteners with genuine OEM parts.
