Audi part number N10106403 is a Genuine Volkswagen/Audi Hexagon Collar Self-Locking Nut.
Technical Specifications:
Size: M12 x 1.5mm
Type: Hexagon with a built-in collar, self-locking (frequently designated by Audi as a "one-time use" or "always replace" stretch nut for safety).
Supercession/Replaces: This part number directly replaces the older part number N10106402.
Common Applications & Positions:
Because it is a highly versatile standard hardware size for structural chassis components, it is used across almost all Audi models (A3, A4, A6, A8, Q5, Q7, TT, etc.) for various critical suspension and steering points. Depending on your specific vehicle's layout, it most frequently secures:
Control Arms: Front or rear lower/upper control arm ball joints and inner pivot mounts.
Struts & Shocks: The front strut pinch bolt or upper strut mount/shock absorber mounts.
Steering & Knuckles: Steering knuckle-to-arm mounting points and tie rod ends.
Sway Bars: Suspension stabilizer bar links.
Note: Since self-locking nuts lose their locking capability once removed, factory service manuals always recommend using a brand-new nut whenever you disassemble these suspension components.
