OVERVIEW
Factory fine-thread bolt for the assigned suspension joint
N-106-022-02 is the Genuine VW/Audi M12 x 1.5 x 75 suspension control arm bolt for the rear axle connection identified in the fitment table. The fine thread, shank length and head arrangement are part of the original joint specification.
Suspension fasteners maintain the clamp load that holds the connected components together. A bolt that merely fits through the opening can still have an unsuitable thread pitch, working length or bearing surface.
Technical details
- Complete factory number: N-106-022-02.
- Factory specification: M12 x 1.5 x 75 mm.
- Design: hexagon-head combination suspension bolt.
- Quantity supplied: one individual bolt.
M12 is the nominal thread diameter, 1.5 mm is the thread pitch and 75 mm is the nominal bolt length. Match the complete factory number at the exact connection rather than selecting hardware by diameter alone.
Common reasons to replace
- The bolt has been removed from a connection that requires new hardware.
- The threads are damaged, stretched or cross-threaded.
- The head or bearing surface is damaged.
- Corrosion prevents reliable seating or controlled tightening.
- A previous repair installed an incorrect fastener.
Inspect the mating nut or threaded receiver, control arm and mounting surfaces. Replacing the bolt alone does not correct a damaged bushing, distorted bracket or worn suspension joint.

Installation guidance
Support the vehicle and suspension safely and follow the factory procedure for the exact joint. Use new mating hardware wherever specified, observe any required suspension loading position and apply the prescribed torque and angle sequence.
Verify secure seating and complete any required alignment checks after the suspension repair. Do not reuse this bolt when the applicable procedure specifies replacement.
