OVERVIEW
Genuine VW/Audi collared hex nut, part number N-106-092-03. This original M8 x 1.25 fastener is cataloged at specified horn, alternator and stabilizer-bar bracket attachments. The table below identifies the exact confirmed mounting uses for each vehicle configuration.
Technical details
- Original number: N-106-092-03 / N10609203.
- Published nominal thread size: M8 x 1.25.
- External hex with an integral collar beneath the nut.
- Cataloged earlier number: N10609202.
- One nut supplied. Horn, alternator, stabilizer components and other hardware are separate.
The collar forms the nut's contact surface at its assigned mounting connection. Correct thread engagement and component seating are necessary for assembling the attachment as designed. The nut must be matched to the original number and actual mounting position.
The confirmed electrical and suspension uses require different repair procedures. A shared part number does not make their tightening instructions interchangeable, and another M8 nut can differ in pitch, collar or other features.
Common reasons to replace
Replace missing hardware, damaged internal threads, a rounded hex, deformation or corrosion affecting installation. Follow the applicable factory requirement to renew nuts after removal.
The confirmed A5 Sportback stabilizer-bracket catalog explicitly identifies the nut as unsuitable for reuse after removal. Use replacement hardware for that attachment and follow the exact suspension procedure.
Horn or alternator service can expose an incorrect substitute nut or a damaged mating stud. Inspect the mounting component and threads before reassembly. A new nut cannot repair a failed electrical component, cracked bracket or damaged threaded mounting point.
Suspension noise or a loose stabilizer attachment requires inspecting the bracket, bushing and related components. Correct the actual defect before assembling replacement hardware; do not overtighten the nut to compensate for component damage.
Installation and service notes
Identify the exact mounting position in the fitment table and follow its factory procedure. For alternator or horn work, follow the required electrical isolation instructions before servicing the component.
Inspect the mating stud and contact surfaces, align the component correctly and start the nut by hand on undamaged threads. Do not use the nut to force a misaligned bracket into position.
Use the correct socket and tightening specification for the actual connection, including any required additional angle. Horn, alternator and stabilizer-bracket attachments can have different specifications.
Do not infer torque from the M8 x 1.25 size. Follow the specified thread preparation and hardware replacement requirements. If the nut binds or the component does not seat normally, inspect the mounting parts before proceeding.
Complete the applicable electrical or suspension checks after service. This listing contains one original nut and does not include a complete installation kit. Select other fasteners separately for the actual repair.
