OVERVIEW
Factory combination bolt for the front wishbone connection
N-910-166-02 is the Genuine VW/Audi M12 x 1.5 x 85 hexagon-head combination bolt for the assigned front control arm mounting positions below.
The original washer arrangement provides the bearing surface required by the connection. Select by full part number and joint location: several neighboring suspension bolts have different working lengths, thread sizes and bearing designs.
Technical details
- Complete factory number: N-910-166-02.
- Factory specification: M12 x 1.5 x 85 mm.
- Design: external hexagon-head combination bolt with washer arrangement.
- Quantity supplied: one individual bolt.
M12 is the nominal thread diameter, 1.5 mm the thread pitch and 85 mm the catalog bolt length. The listing supplies one fastener; it does not include a control arm, bushing or mating nut.
Common reasons to replace
- The mounting connection has been dismantled and requires replacement hardware.
- Threads are damaged or cross-threaded.
- The head or washer bearing surface is damaged.
- The shank is bent or corrosion prevents proper seating.
- The installed bolt is missing or differs from the original specification.
Check the control arm, bushings, mounting bracket and receiver threads. Repair worn or damaged components before assembly. Replacing a bolt alone does not correct a failed bushing or damaged mounting point.

Verify seating and clearance and complete alignment checks required by the repair. Renew other single-use mounting hardware as directed by the vehicle procedure.
