OVERVIEW
Factory Torx combination hardware for body attachments
N-909-493-02 is a Genuine VW/Audi M6 x 15.5 combination bolt with a recessed Torx drive and integrated washer. The confirmed B5 A4 application secures the front fender at the specified factory mounting point after the listed VIN change.
The washer-style bearing surface distributes the attachment load around the fixing point. Correct head profile, length and factory number matter when replacing body hardware, especially where the original bolt passes through a panel flange or bracket.
Technical details
- Complete factory number: N-909-493-02.
- Factory specification: M6 x 15.5 mm combination bolt with Torx drive and integrated washer.
- Design: Rounded head, recessed six-lobe drive and integrated washer-style bearing surface.
- Quantity supplied: one individual bolt.
The nominal fastening size identifies the factory bolt; it does not establish compatibility with every M6 body attachment. Match the complete number and original mounting arrangement.
Common reasons to replace
- A stripped or rounded drive recess that prevents reliable removal or tightening.
- Damaged threads, a bent shank or an impaired washer bearing surface.
- Missing original hardware or an incorrect substitute discovered during fender service.
Check the receiving thread or clip nut, panel flange and adjoining support for damage. A loose or misaligned panel can require correction of its mounting points as well as replacement hardware.

Installation guidance
Support and align the panel before tightening. Start the bolt by hand to avoid cross-threading, retain the original attachment arrangement and use the factory procedure for the exact joint.
Inspect panel alignment and clearance after installation. Replace a damaged receiving nut or mounting clip as required; tightening a new bolt into a damaged attachment will not restore a sound joint.
