OVERVIEW
Genuine VW/Audi WHT-002-129 is an individual self-locking oval-head mounting bolt. It supplies the specifically assigned service hardware at the confirmed radiator-fan electrical-assembly mounting points listed below.
Technical details and what is included
- Factory part number: WHT-002-129 / WHT002129.
- Component: self-locking oval-head bolt.
- Factory nominal designation: M5 × 16.
- Quantity supplied: one individual bolt.
- The archive photo shows the socket-drive head, washer arrangement and threaded shank.
- Verified earlier reference: N-106-095-01 where the current bolt is assigned as the forward replacement.
Match the exact mounting location and factory part assignment. This bolt has other catalog applications, but only the confirmed vehicle configurations below are covered by this fitment table. A similar thread size does not establish that another fastener has the required head, washer or locking specification.
Common reasons to replace
- The assigned bolt is missing during assembly service.
- The drive recess or threads are damaged during removal.
- Damage prevents the bolt from seating correctly at its original mounting point.
- The factory procedure requires renewal of the self-locking hardware.
Inspect the mounting feature and associated assembly before installing a replacement. A damaged bracket, broken attachment or incorrect component alignment requires separate repair. Replacing the bolt alone does not diagnose a radiator-fan electrical fault or an overheating concern.

Installation and service guidance
Use the factory procedure for the installed radiator-fan electrical assembly. Complete the prescribed electrical and access preparation before removing mounting hardware.
Inspect the mating threads and mounting surface, use the tool that matches the actual drive recess and start the bolt correctly. Follow the specified fastening sequence, tightening value and hardware-renewal requirement.
Do not estimate torque from the bolt diameter or assume that a generic M5 fastener provides the required locking arrangement. Replace other damaged screws, mounting features or electrical components with their separately assigned parts.
Verify correct seating and secure retention, then complete the operating checks required for the repaired assembly. This listing supplies one mounting bolt; the fan, control electronics, brackets and wiring are separate.
