OVERVIEW
Genuine M8×26 bolt for the original underbody attachment
The N-910-490-01 Genuine VW/Audi bolt secures the assigned underbody trim and cover attachment on the R8 configurations below. The complete factory number identifies an M8×26 fastener with an internal multipoint drive.
The R8 underbody assembly contains several bolt sizes and receiving clips. Match this exact number and original M8 attachment. This listing supplies one mounting bolt rather than an underbody panel, heat shield, bracket or full hardware set.
Technical details
- Complete factory number: N-910-490-01.
- Factory specification: M8 × 26.
- Design: socket-head bolt with internal multipoint drive and broad bearing arrangement.
- Quantity supplied: one individual bolt.
Correct diameter, length and bearing contact preserve the original attachment geometry. A neighboring M6 trim bolt or another M8 fastener is not automatically suitable. Confirm the original receiving point and hardware arrangement before installation.
Common reasons to replace
- The original bolt is missing after underbody service.
- The internal multipoint drive is damaged.
- Threads are damaged or cross-threaded.
- The head or bearing surface is distorted.
- Incorrect hardware was installed during a previous repair.
Inspect the panel mounting tab, receiving threads and any bracket or clip involved in the original connection. A new bolt cannot repair a torn tab or damaged support. Replace other damaged attachment components as required.
Vehicle fitment
Use only at the original M8×26 underbody attachment assigned N91049001. Observe the Coupe and Spyder configurations and verify the actual receiving position; other fasteners throughout the assembly have different numbers.

Installation guidance
Follow the factory vehicle-support and underbody access procedure. Support the panel or cover, align its attachment without forcing it and start the correct bolt by hand. Use a fully engaged multipoint tool and the connection-specific tightening procedure.
Confirm secure retention and required clearance from moving and hot components. Restore all other original underbody fasteners and check that the serviced cover sits correctly.
Ordering information
