Brake Disc Mounting Screw - M6 x 12
Sold each - 2 required per disc
Maintain secure and accurate brake disc installation with
this OE Match Brake Disc Mounting Screw 90026904701. Used across a wide range
of Porsche models, this small but essential fastening component secures the
brake disc (rotor) to the wheel hub during assembly and servicing.
Fits:
- Porsche 911
- Porsche 924S
- Porsche 944
- Porsche 964
- Porsche 993
- Porsche 996
- Porsche 997
- Porsche Boxster 986
- Porsche Boxster 987

Although the wheel bolts ultimately clamp the brake disc firmly against the hub, the brake disc mounting screw plays an important role in keeping the disc correctly aligned during installation. This ensures accurate positioning of the brake rotor, simplifies wheel and brake servicing and helps prevent movement while the wheel is removed.
Due to repeated exposure to heat, corrosion, moisture and brake servicing, these screws can become seized, damaged or stripped over time. Replacing the mounting screw whenever the brake discs are renewed helps ensure trouble-free future maintenance and correct brake assembly.
What Does a Brake Disc Mounting Screw Do?
The brake disc mounting screw secures the brake disc to the wheel hub before the wheel is fitted.
Its primary functions include:
- Locating the brake disc correctly on the hub
- Maintaining disc alignment during assembly
- Preventing disc movement when the wheel is removed
- Simplifying brake servicing
- Supporting accurate brake disc installation
- Assisting wheel and hub assembly procedures
- Helping maintain factory brake fitment standards
Although small, this component plays an important role in brake system maintenance and assembly.
Why Do Brake Disc Mounting Screws Fail?
Brake mounting screws operate in a harsh environment and are frequently removed during brake servicing.
Common causes of failure include:
- Corrosion and rust
- Heat cycling from braking systems
- Rounded or stripped screw heads
- Seized threads
- Improper removal techniques
- Galvanic corrosion between metals
- Age-related deterioration
- Repeated brake servicing
It is common for original screws to become difficult to remove after years of service.
When Should Brake Disc Mounting Screws Be Replaced?
Brake disc mounting screws should always be inspected during brake maintenance.
Replacement is recommended when:
- Installing new brake discs
- Screw heads become damaged
- Threads show signs of wear
- Corrosion is present
- Screws become seized during removal
- Carrying out brake refurbishment work
- Restoring older Porsche models
- Performing preventative maintenance
Many Porsche specialists routinely replace retaining screws during brake disc replacement to avoid future servicing issues.
Why Replacement Matters
Replacing worn or corroded brake disc mounting screws helps ensure correct brake assembly and easier future maintenance.
Benefits include:
- Secure brake disc location
- Easier brake servicing
- Reduced risk of seized hardware
- Improved assembly accuracy
- Better long-term reliability
- Prevention of damaged hub threads
- Restoration of factory fitment standards
- Professional-quality brake maintenance
A new retaining screw is an inexpensive but worthwhile addition to any brake overhaul.
