OVERVIEW
Genuine speed nut for the original front-seat hardware position
N-910-558-02 is the Genuine VW/Audi speed nut used at the specified front-seat assembly attachment. The factory designation is M5×29.4×20.3.
This formed retaining nut provides the receiving point for its assigned screw. It belongs at a specific position within the original seat assembly and is separate from the seat-to-body mounting bolts and other seat fasteners.
Technical details
- Complete factory number: N-910-558-02.
- Factory specification: M5 × 29.4 × 20.3.
- Design: formed seat-assembly speed nut.
- Quantity supplied: one individual speed nut.
The factory designation identifies the M5 receiving size and nominal retaining-nut dimensions. Shape, engagement and mounting location must match the original part. A generic M5 nut is not automatically a suitable replacement.
Common reasons to replace
- The nut is missing after seat or trim service.
- The screw no longer engages securely.
- The retaining nut is bent or distorted.
- The mounting engagement is damaged.
- An incorrect nut was installed in the original position.
Inspect the supporting tab, original screw and surrounding seat component. A replacement nut cannot restore a broken mounting tab or compensate for an incorrectly sized screw. Check the actual seat configuration before selecting hardware.

Installation guidance
Follow the vehicle-specific seat and trim access procedure, including any electrical disconnection steps it requires. Fit the nut in the original orientation, align the mating component and start the correct screw without forcing or cross-threading it.
Confirm the serviced component is retained correctly and that seat movement and surrounding trim clearance are unobstructed. Restore any removed covers and connectors according to the service procedure.
