This lock nut fits in the steering and chassis assembly, commonly used at the steering rack tie rod end / track rod end connection. Depending on model and application, M12 x 1.5 lock nuts may also appear in suspension and control arm fastening locations.

This is a small but important OE Porsche hardware item that helps secure critical chassis and steering components to the correct factory standard.

Functions
•  Secures the steering rack tie rod end connection
•  Provides a factory-correct M12 x 1.5 locking fastening point
•  Helps maintain secure attachment of steering and chassis components
•  Supports correct steering geometry and component stability
•  Helps prevent loosening caused by vibration, road loads and suspension movement
•  Suitable for replacement during steering rack, track rod or tie rod end work
•  Maintains OE Porsche fitment and fastening quality.

Lock nuts are designed to provide secure fastening and are often recommended for replacement after removal, especially on steering and suspension components. Over time, the nut can corrode, seize, round off or lose its locking effectiveness. Replacing the original nut with a Genuine Porsche OE M12 x 1.5 lock nut helps ensure the tie rod end or related component is secured correctly and safely. This is especially important on steering components, where correct fastening is essential for accurate steering response and road safety.

When to replace
•   When replacing a steering rack tie rod end or track rod end
•   When removing or refitting steering rack components
•   If the original nut is corroded, seized or damaged
•   If the nut thread is worn or the locking function is compromised
•   During suspension or steering overhaul work
•   After accident repair or chassis component replacement
•   When restoring the car with correct OE Porsche hardware.
