OVERVIEW
Genuine VW/Audi collared hex nut, part number N-104-018-01. This original fastener is cataloged at multiple suspension attachments. The fitment table below identifies confirmed rear suspension profiles using the exact original hardware number.
Technical details
- Original part number: N-104-018-01 / N10401801.
- Published nominal thread size: M14 x 1.5.
- Hex nut with an integral collar beneath the drive surfaces.
- Supplied individually for the specified factory connection.
- Control arm, bolt, washers, wheel carrier and other hardware are separate.
The collar provides the contact surface beneath the nut at the original fastening arrangement. Correct hardware selection is necessary to retain the suspension joint according to the designed assembly.
Match the part number and exact mounting location before ordering. A nut with the same nominal diameter can differ in pitch, collar form or fastening specification. This number does not identify every control-arm, shock or link nut on the vehicle.
Common reasons to replace
Replace a missing nut, damaged threads, rounded drive surfaces, visible deformation or corrosion affecting the fastener. Renew hardware when required by the applicable repair procedure after suspension removal or adjustment.
Control-arm replacement or related suspension work can expose damaged mating bolts and attachment points. Inspect the full connection before fitting new hardware, especially if the original joint was loose or difficult to dismantle.
A new nut does not repair a worn bushing, damaged control arm, defective joint or deformed mounting point. Suspension noise, abnormal tire wear and handling concerns require diagnosis of the complete assembly.
Installation and service notes
Support the vehicle and suspension as prescribed by the repair procedure. Identify the exact attachment and original hardware number before disassembly. Adjacent suspension joints can require different bolts, nuts and tightening methods.
Start the correctly specified nut by hand on undamaged mating threads. Ensure that the bolt, washers and suspension components are seated in their intended order before tightening.
Follow the factory tightening specification and sequence for the actual connection. Apply any required suspension loading position when the procedure calls for it. Do not infer torque from the M14 x 1.5 thread size or transfer a specification from another joint.
Replace non-reusable hardware as directed and use thread treatments only when specified. If the nut does not engage or seat normally, inspect thread compatibility and component alignment instead of applying excessive force.
Complete the required suspension and alignment checks after the repair. This listing supplies one original nut, rather than a complete control-arm installation kit.
