This essential steering assembly fastener is responsible for securing the steering wheel to the steering column shaft, helping maintain a firm and reliable connection between the driver's steering input and the vehicle's steering mechanism.
Although small in size, the steering wheel fastening nut performs a critical safety function. The steering wheel must remain securely attached to its shaft to maintain dependable steering control.
The Porsche 356 steering system uses a mechanical connection between the steering wheel hub and the steering shaft. The fastening nut holds this assembly together, preventing unwanted axial movement of the steering wheel.
On classic Porsche vehicles, original steering wheel fasteners may have experienced decades of use, repeated removal during restoration work, corrosion or damage from incorrect tools.
Over time, the nut's threads or hexagonal driving surfaces may become worn, rounded or damaged.
An incorrectly fitted or deteriorated fastening nut may no longer provide the necessary clamping force to hold the steering wheel securely.
This can result in unwanted steering wheel movement or, in severe cases, compromise the security of the steering wheel mounting.
The OE MATCH replacement nut, corresponding to original Porsche reference 35647201, provides a practical solution when the existing fastener is damaged, missing or unsuitable for reuse.
It is particularly useful during steering wheel removal, steering column repairs, interior refurbishment and classic Porsche restoration projects.
The component is designed for the original-style steering wheel mounting arrangement found on compatible Porsche 356 Pre-A and 356A vehicles.
Its hexagonal form allows the nut to be tightened using the appropriate tool and Porsche workshop procedure.
Unlike decorative steering wheel trim, this component is a safety-critical mechanical fastener and must be installed correctly.
What This Product Does:
The steering wheel fastening nut secures the steering wheel hub to the threaded end of the steering shaft.
Its primary functions include:
- Secures the Steering Wheel: Holds the steering wheel firmly in its intended position on the steering column shaft.
- Maintains Steering Wheel Retention: Prevents unwanted movement of the wheel along the shaft.
- Provides Mechanical Clamping Force: Keeps the steering wheel hub correctly seated against its mounting arrangement.
- Supports Reliable Steering Operation: Helps maintain a secure connection between the steering wheel and steering mechanism.
- Prevents Excessive Steering Wheel Movement: Restricts looseness caused by an inadequately secured hub.
- Maintains Original-Style Assembly: Preserves the correct fastening arrangement of the classic Porsche 356.
- Supports Steering System Maintenance: Provides a replacement when the original nut is damaged during removal.
- Suitable for Restoration: Helps complete the reassembly of an original or properly compatible replacement steering wheel.
Symptoms Of Wear Or Failure:
Steering wheel fastening nuts are generally durable components and do not require routine replacement at fixed service intervals.
However, damage, corrosion or previous incorrect installation may make replacement necessary.
Possible symptoms:
- Steering wheel movement towards or away from the dashboard.
- A clicking or knocking sensation at the steering wheel centre.
- Movement between the wheel hub and steering shaft.
- A steering wheel that does not feel securely mounted.
- Difficulty threading the nut onto the steering shaft.
- The nut binding or turning unevenly.
- Visible thread damage.
- Inability to achieve the correct tightening torque.
- The nut failing to hold its position securely.
- Rounded corners.
- Tool slippage during removal.
- Difficulty applying the correct tightening force.
- Visible deformation of the nut.
Why Replacement Matters:
The steering wheel fastening nut is a critical part of the driver's steering control system.
Replacing a damaged, missing or unsuitable fastener is important for maintaining the secure mounting of the steering wheel.
- Restores Steering Wheel Retention: Helps secure the steering wheel to the steering shaft.
- Supports Vehicle Safety: Maintains a critical mechanical connection within the steering system.
- Eliminates Damaged Fastening Hardware: Replaces nuts with worn or stripped threads.
- Helps Prevent Unwanted Wheel Movement: Maintains the intended axial retention of the steering wheel hub.
- Provides Correct Original-Style Fitment: Corresponds to Porsche reference 35647201.
