OVERVIEW
Genuine VW/Audi self-locking collared hex nut, part number N-102-861-10. This original fastener has multiple suspension uses. The fitment table below identifies confirmed upper-control-arm ball-joint pinch-bolt attachments at the steering knuckle, keeping the exact hardware arrangement clear.
Technical details
- Original part number: N-102-861-10 / N10286110.
- Published nominal thread size: M10 x 1.5.
- Self-locking hex nut with an integral collar, supplied individually.
- Cataloged earlier number: N10286102.
- The listed pinch-attachment profiles reference the original nut with bolt N10425302.
- Bolt, control arms, ball joints, steering knuckle and other hardware are separate.
The collar provides the contact surface beneath the nut, while the self-locking specification forms part of the original retention arrangement. Thread diameter alone is insufficient to select hardware for a suspension connection; match the part number and mounting position.
Common reasons to replace
Replace a missing nut or one with damaged threads, a rounded drive surface, visible deformation or corrosion that has compromised its condition. Renew self-locking hardware when the applicable factory procedure requires replacement after removal.
The upper-control-arm pinch attachment can be difficult to dismantle when the bolt has corroded in the knuckle. If removal damages the nut or bolt, inspect the entire connection and use the required replacement hardware.
Check the control-arm joint seating and the knuckle attachment before reassembly. A damaged joint, cracked mounting area or defective mating bolt cannot be repaired by installing a new nut alone. Suspension noise and handling concerns require diagnosis of the complete assembly.
Installation and service notes
Support the vehicle and suspension using the factory procedure. Identify the exact pinch-bolt connection and confirm the original hardware numbers before ordering. Other stabilizer or suspension mounting uses can require different bolts, specifications or part numbers.
Ensure that the joints are correctly seated and the specified bolt is correctly installed before starting the nut by hand. Follow the prescribed tightening specification and sequence for this connection.
Do not derive a torque from the M10 x 1.5 thread size or transfer a value from a stabilizer link, shock attachment or another chassis. Use thread treatment and any required counter-holding method only as directed by the repair instructions.
Inspect mating threads and the mounting area if tightening is abnormal. Do not use excessive force to compensate for damaged hardware or an incorrectly seated joint. Complete the required suspension and alignment checks after the repair.
This listing supplies one original nut. It is not a complete pinch-bolt kit, an adjustable control arm or a replacement steering knuckle.
