OVERVIEW
Factory M10 x 85 hardware for the assigned suspension connection
N-912-216-01 is the Genuine VW/Audi M10 x 85 suspension control arm bolt for the confirmed applications below. The original working length and combination bearing arrangement suit the specific mounting joint.
Suspension assemblies use different bolts at neighboring mounting positions. Identify the exact joint and complete factory number so that the replacement has the correct engagement and bearing geometry.
Technical details
- Complete factory number: N-912-216-01.
- Factory specification: M10 x 85 mm.
- Design: hexagon-head combination bolt with bearing washer arrangement.
- Quantity supplied: one individual bolt.
M10 denotes the nominal thread diameter and 85 mm is the catalog bolt length. The selected Q8 and RS Q8 catalogs identify this fastener as hardware that cannot be reused or reinstalled after removal.
Common reasons to replace
- The assigned suspension connection has been dismantled and requires a new bolt.
- The threads are damaged or cross-threaded.
- The hexagon head or bearing surface is damaged.
- Corrosion prevents secure seating or controlled tightening.
- The original fastener is missing or has been replaced with incorrect hardware.
Inspect the arm, bushing, bracket and mating receiver before assembly. Damaged or worn suspension components require their own repair; installing a new bolt alone does not correct movement elsewhere in the joint.

Installation guidance
Use new hardware and follow the vehicle-specific suspension procedure. Support the components safely, observe any required loaded-suspension tightening position and apply the prescribed torque and angle sequence for the exact joint.
Check that the bearing surfaces seat correctly and complete the alignment and functional checks required for the repair. Renew associated nuts or other bolts wherever the factory procedure requires replacement.
