Plastic Nut A 000 990 31 62

Ensure secure, rattle-free attachment of your Mercedes-Benz’s trim pieces and plastic panels with the genuine plastic nut (part A 000 990 31 62). This OEM-specified nylon nut features precisely molded threads and a locking design to maintain clamp force without metal-to-metal corrosion.

Key Benefits

• Exact OEM Specification
  Threads and flange dimensions match factory hardware for seamless drop-in replacement—no adapters or modifications required.

• High-Strength Nylon Construction
  Automotive-grade nylon resists heat, vibration and chemical exposure without cracking or deforming.

• Corrosion-Proof Performance
  Non-metallic design eliminates rust, ensuring long-term reliability in damp or salty environments.

• Integrated Flange & Lock Feature
  Wide flange distributes load over a larger area, while the nylon locking strip grips the bolt threads to prevent loosening under vibration.

2. Hand-Thread Nut: Engage the plastic nut onto the bolt by hand, ensuring threads align to avoid cross-threading.

3. Torque to Spec: Use a spinner bit or hand tool; tighten gently until the flange contacts the panel—do not over-torque to prevent nylon deformation.

4. Verify Fitment: Check that the panel sits flush and the nut remains tight without play.
