OVERVIEW
Genuine VW/Audi WHT-001-273 is an individual mounting bolt used at the specified original glass sliding-sunroof attachment point. Renewing damaged or missing roof hardware with the correctly assigned part helps restore the factory mounting arrangement during sunroof service.
Technical details and what is included
- Factory part number: WHT-001-273 / WHT001273.
- Application: assigned sunroof-glass or guide mounting point.
- Factory nominal hardware designation: M5 × 16.
- Quantity supplied: one individual mounting bolt.
- The original photo shows the socket-drive head, washer arrangement and threaded shank.
- Verified earlier reference numbers: 6N0-877-721 and 8D0-877-721-A where the current part is assigned as the forward replacement.
Confirm the original bolt assignment, roof type and mounting location before ordering. A catalog vehicle quantity or warehouse order quantity does not describe the quantity supplied by this listing. Glass panels, sunroof guides, seals and operating mechanisms are separate parts.
Common reasons to replace
- A bolt is missing from the specified glass mounting point.
- The drive recess is damaged and no longer accepts the correct tool securely.
- Threads or the washer arrangement are damaged during service.
- The factory procedure requires fresh mounting hardware during glass or guide replacement.
Inspect the mating attachment and roof mechanism before installation. Missing hardware can require adjustment and a complete mounting inspection. A replacement bolt alone does not resolve a damaged guide, an incorrectly aligned glass panel, a drain blockage or a deteriorated roof seal.

Installation and service guidance
Follow the factory procedure for the vehicle's installed roof system. Support and position the glass as specified before loosening its fasteners. Use the tool that matches the actual drive recess and inspect the mating threads before installing the replacement.
Keep track of the original mounting locations and replace other damaged hardware with its separately assigned number. Follow the specified tightening sequence, torque and any thread-treatment requirements; do not estimate tightening force or substitute a generic screw based only on diameter.
Complete the required glass-height and alignment checks after mounting. Verify normal roof operation, clearance and seal contact using the factory procedure. Inspect drains, guides and seals separately when addressing water ingress or operating problems.
This listing provides one small mounting bolt. The sunroof glass panel, roof assembly, guide repairs and seals are not included.
