OVERVIEW
Genuine interior and audio attachment hardware
The N-910-851-01 Genuine VW/Audi bolt is used at the original interior and speaker-system mounting points listed below. Verified applications include the assigned multimedia hardware in the A4 Avant, the specified premium sound installation in the Q5 and glove-box mounting hardware in the listed R8 Spyder.
Each row identifies a particular connection. The Q5 speaker application requires the PR 9VK sound package, while the A4 row is restricted to the Avant body. This bolt is not a universal replacement for every interior screw on those vehicles.
Technical details
- Complete factory part number: N-910-851-01.
- Nominal factory specification: M5 × 16.
- Factory design: semi-round combination-head mounting bolt.
- Applications: assigned interior/audio and glove-box mounting connections.
- Unit supplied: one bolt.
The nominal specification identifies the threaded fastener rather than a packaged shipping dimension. Match the head seating arrangement, receiver and original attachment point. Other fasteners in the same sound system or interior panel can have a different thread diameter or length.
Common reasons to replace
- A mounting bolt is missing after audio or interior service.
- The drive is damaged or rounded.
- The threads have been crossed or damaged.
- The head or bearing surface no longer seats correctly.
- A previous repair used incorrect fastening hardware.
Inspect the speaker mounting point, glove-box bracket or relevant receiver before assembly. A new bolt cannot repair a cracked housing, broken bracket or stripped receiver. Loose trim, rattles and audio faults require diagnosis of the affected assembly rather than assuming a new fastener will resolve every symptom.
Vehicle fitment
The table preserves the exact body and sound-package requirements. Compare the factory PR codes and original fastening position where specified. The R8 application refers to the glove-box mounting connection.

Installation guidance
Follow the factory procedure for the specific audio or interior component being serviced. Observe the prescribed steps for adjacent electrical or restraint-system components and protect surrounding trim during access. Keep the original mounting hardware identified.
Align the component before carefully starting the bolt in the original receiver. Use the correct tool for the actual drive and follow the tightening instruction for the exact connection. Do not add washers or tightening force to compensate for a damaged or misaligned mounting point.
After reassembly, verify secure retention and correct seating of the serviced component. Restore electrical connections and carry out the required functional checks if the audio system or other electrical equipment was disturbed.
Ordering information
