OVERVIEW
Genuine M5 screw-receiving clip nut
The N-907-777-04 Genuine VW/Audi speed nut provides the assigned M5 threaded attachment in the original mounting arrangements listed below, including audio-equipment brackets, a rear bumper retaining point and a radiator-support attachment.
The A4 and A6 rows require different sound-package codes. Match the original bracket and complete clip number rather than assuming that every radio or amplifier installation uses the same hardware. Other speed nuts in these assemblies have different thread sizes.
Technical details
- Complete factory number: N-907-777-04.
- Factory specification: M5 × 13.6 × 11.5.
- Design: clip-on threaded speed nut for the original equipment bracket.
- Quantity supplied: one individual clip nut.
The catalog specification identifies the thread and clip arrangement rather than packaged shipping dimensions. This M5 receiver must be paired with the correct screw and mounting edge. Similar-looking panel-screw clips and M6 threaded clips are not interchangeable.
Common reasons to replace
- The clip nut is missing after equipment removal.
- The threaded receiver is stripped or crossed.
- The clip is bent and no longer grips its bracket.
- The bearing surface or threaded portion is damaged.
- A previous installation used incompatible mounting hardware.
Inspect the bracket, screw, mounting edge and nearby wiring. A replacement clip nut cannot repair a cracked bracket or stripped mating screw. Audio faults require separate diagnosis of the equipment and electrical system.
Vehicle fitment
Match the component location in each row. The audio applications require A4 PR 9VK or A6 BOSE PR 8RY. The TT/TTS bumper and Q3 radiator-support applications are separate uses and do not inherit those audio-package restrictions.

Installation guidance
Follow the factory removal and installation instructions for the specific equipment bracket, bumper retaining point or radiator support. Protect connectors and wiring, position the replacement nut on the original mounting edge and align the specified M5 screw before engaging its threads. Use the prescribed tightening instruction for the exact attachment.
Confirm that the clip remains seated, the equipment is securely supported and wiring is routed without tension or pinching. Restore any trim and complete the prescribed functional checks after service.
