OVERVIEW
Genuine Shouldered Hex Fastening Nut
The N-015-081-6 Genuine VW/Audi shouldered hex nut restores the specified fastening hardware at the original attachment point. Its M12 diameter, 1.5 mm thread pitch and integrated shoulder must match the original bolt or stud and bearing surface. This listing supplies one individual nut; mating fasteners, washers, links and control arms are separate.
For the listed Audi A3 8P applications, this is the front lower ball-joint stud nut at the steering knuckle. It is separate from the three smaller M10 nuts that attach the ball joint to the control arm. Inspect the stud threads and seating surface during ball-joint service and replace damaged or incorrectly substituted hardware.
Technical Details
- Original part number: N-015-081-6.
- Thread diameter: M12.
- Thread pitch: 1.5 mm.
- Design: external hex nut with integrated shoulder.
- Quantity supplied: one nut.
The shoulder provides the specified contact area against the mating component. Correct thread pitch is essential: another M12 nut with a different pitch will not engage properly and can damage the bolt or stud. Do not substitute a generic nut based on diameter alone.
Cataloged uses include stabilizer link and suspension control arm fastening, with other applications depending on the vehicle and attachment point. Volkswagen bulletin V401801 identifies this exact nut for the 2018–2019 Atlas front coupling rod repair. The bulletin specifies two nuts for that repair; this listing is sold individually.
Common Reasons to Replace
- The original nut is removed during suspension link or related component service and renewal is required.
- The threads or hex flats are damaged.
- Corrosion has compromised the bearing surface or tool engagement.
- The nut is missing after a repair.
- A previous repair installed a nut with the wrong pitch or bearing geometry.
Movement or noise at a suspension joint can also result from a worn link, bushing, mounting hole or damaged mating fastener. Inspect the complete assembly. A replacement nut cannot repair stripped threads, a bent bracket or a failed joint.
Installation and Service Notes
Confirm the original fastening position, mating bolt or stud, and parts diagram. Use the correct tool and follow any counter-hold procedure for the joint. Fit new hardware where the repair instructions specify it.
Use the tightening procedure for the exact attachment point. Thread diameter alone does not establish torque, and some suspension joints require a specified vehicle position during tightening. Do not add lubricant, thread treatment or extra washers unless the workshop procedure calls for them. Replacement or modified suspension components can require different hardware from the factory assembly.
