OVERVIEW
Original oval-head combination hardware
WHT-003-497 is a Genuine VW/Audi M8 x 23 oval-head bolt with an internal hex drive and washer-style bearing arrangement. Its confirmed applications include the specified A7 door-check attachment and a separate CC underbody fastening point.
The same complete bolt number can serve different body assemblies. Match the actual attachment as well as the vehicle: this is one individual fastener, not a door check, latch, underbody panel or mounting kit.
Technical details
- Complete factory number: WHT-003-497.
- Factory specification: M8 x 23 mm oval-head internal-hex combination bolt.
- Design: Rounded head with recessed six-sided drive and washer-style bearing arrangement.
- Quantity supplied: one individual bolt.
M8 x 23 describes nominal fastening dimensions. No unverified thread pitch, drive-bit size, strength class, tightening torque, shipping weight or package size is supplied.
Common reasons to replace
- A damaged hex recess that no longer permits controlled tightening.
- Damaged threads, a bent shank or an impaired head bearing surface.
- Missing hardware, an incorrect substitute or removal of door-check hardware identified as non-reusable.
Door clicking or poor control can also come from a worn check mechanism, loose bracket or damaged attachment. Underbody rattles can come from a damaged shield or retainer. Inspect the relevant assembly before assuming a replacement bolt alone will resolve the symptom.
Vehicle fitment
Match both the vehicle and the fastening role in the table. Door-check and underbody entries are separate uses of the same factory bolt.

Installation guidance
Support the door or attached panel before loosening its hardware. Preserve the factory spacer and washer arrangement, and follow the tightening procedure for the exact joint.
Use fresh door-check mounting hardware where the dealer catalog prohibits reuse. Confirm door-check operation, attachment security and component clearance after service.
