OVERVIEW
Restore the captive threaded body trim attachment
6L0-809-864 is the Genuine VW/Audi M6 rivet nut used at the body trim and side-panel insert positions listed below. The insert provides a captive receiving thread within the original mounting opening.
A securely set insert lets its mating fastener clamp the attached component without needing a loose nut behind the panel. Its body and retaining flange must match the original receiving area and factory setting procedure.
Technical details
- Complete factory number: 6L0-809-864.
- Factory specification: M6; complete catalog designation M6/1–4-F.
- Design: flanged rivetted threaded insert.
- Quantity supplied: one individual rivet nut.
Match the complete original part number and attachment position. The receiving thread size alone does not establish interchangeability with other M6 rivet inserts or later part revisions.
Common reasons to replace
- The insert turns in its mounting opening.
- The receiving thread is stripped or damaged.
- The original insert is missing after trim or body repair.
- The insert body or retaining flange is distorted.
- The factory body repair procedure calls for a new insert.
Inspect the mounting hole and surrounding panel material. A distorted or enlarged opening requires the specified repair before a new insert can retain securely.
