NISSAN 26391-VB000 Side Combination Lamp Screw Grommet

This genuine Nissan (OEM: 26391-VB000) side combination lamp screw grommet is a premium-quality factory fastener designed specifically for the secure and stable mounting of vehicle lighting assemblies.

Function and Importance

The mounting grommet plays a key role in securing the combination lamps to the vehicle body. Seated in the sheet metal hole, it receives the retaining screw, preventing direct metal-to-metal contact. This minimizes the risk of corrosion at the mounting points. Furthermore, it dampens vibrations generated during vehicle movement, protecting the lamp housing and bulbs from shock damage, while ensuring a precise fit and adequate sealing against moisture.

Technical Specifications

• Material: High-strength automotive-grade polymer (nylon/polyamide), offering superior resistance to environmental factors, UV radiation, and temperature fluctuations.
• Design: Special expanding/snap-in sleeve that firmly locks into the body panel hole when the screw is tightened.
• Installation Position: Side combination lamp mounting points (tail lamps, turn signals).
• Corrosion Protection: Prevents direct contact between the retaining screw and the vehicle body, inhibiting galvanic corrosion.

Signs of Wear or Failure

• Material Fatigue: Over time, the plastic becomes brittle and may crack or break, particularly during lamp replacement or removal for maintenance.
• Loose Lamp Housing: If the internal thread or retaining tabs of the grommet are worn, the lamp cannot be fastened securely, leading to rattling or displacement.
• Water Ingress: A damaged or missing fastener can allow water to penetrate into the luggage compartment or reach the electrical connectors behind the lamp assembly, potentially causing short circuits.
