Featuring an M10x1 fine thread and slotted design for split-pin retention, it helps maintain secure fastening of suspension components.
What Does It Do?
The castle nut secures suspension components to their mounting points.
Its castellated slots allow a split pin to retain the nut, helping prevent loosening during vehicle operation.
Why Does It Fail?
Common causes include:
- Corrosion and age-related deterioration
- Damaged or worn threads
- Overtightening during installation
- Deformed castellated slots
- Damage during removal or servicing
When Should It Be Replaced?
Replace if the nut has damaged threads, corrosion, deformation or worn locking slots.
Replacement is also recommended when the existing nut cannot be securely retained with the correct split pin.
Checks & Installation
Inspect the mating threads and mounting components for wear or damage.
Tighten to the appropriate Porsche workshop specification and secure with a new split pin where required.
Do not reuse damaged fastening components or substitute an incorrect thread size.
Key Features
- OE Match replacement castle nut
- M10x1 fine-thread specification
- Castellated design for split-pin retention
- Suitable for selected Porsche 356 suspension applications
- Ideal for classic Porsche restoration and servicing
