LONG Brake Wheel Mounting Bolt, 40MM.
Restore safe and secure wheel installation with this OE Match Long Brake Wheel Mounting Bolt, 40mm, manufactured as a direct replacement. Produced to OE-style specifications, this precision-engineered 40mm wheel bolt provides the correct thread engagement and clamping force required to securely fasten the wheel to the hub. It is designed for Porsche models requiring a longer mounting bolt, including applications with specific brake assemblies, factory-approved wheel spacers, or wheels that require increased bolt length.

Fits:
  • Porsche 356 1950-55
  • Porsche 356A 1955-59
  • Porsche 356B 1959-63
  • Porsche 356C 1963-65  

As a critical fastening component, the wheel mounting bolt ensures the wheel and brake assembly remain securely attached to the hub under all driving conditions. Over time, wheel bolts can become corroded, suffer thread damage, stretch through repeated incorrect tightening, or develop rounded heads from improper tool use. This OE Match replacement restores factory-style fitment, safety, and reliability, making it ideal for routine maintenance, repairs, and Porsche restoration projects.  

What This Product Does:
  • Secures the wheel safely to the hub assembly.
  • Provides the correct 40mm thread engagement where specified.
  • Delivers the correct clamping force between the wheel and hub.
  • Supports vehicles requiring longer wheel mounting bolts.
  • Replaces worn, damaged, or corroded original fasteners.
  • Ensures safe wheel retention under all driving conditions.
  • Provides an OE-style fit and dependable performance.

Symptoms Of Wear Or Failure:
  • Corroded or heavily rusted wheel bolts.
  • Damaged or stripped threads.
  • Rounded or worn bolt heads.
  • Difficulty achieving the correct tightening torque.
  • Stretched or overtightened wheel bolts.
  • Incorrect bolt length fitted during previous repairs.
  • Signs of damage after repeated wheel removal.
  • Age-related deterioration of the original fasteners.

Why Replacement Matters:

  • The wheel mounting bolt is a critical safety component that provides the clamping force required to securely fasten the wheel to the hub. A damaged, corroded, stretched, or incorrectly sized bolt can compromise wheel retention, resulting in uneven clamping, vibration, damaged threads, or, in severe cases, wheel fastening failure.
  • Replacing worn or incorrect wheel mounting bolts restores safe wheel attachment and ensures the correct factory-style fit and clamping performance. Manufactured as a direct replacement for the original component and produced to OE-style specifications, this OE Match 40mm long brake wheel mounting bolt provides reliable strength, precise fitment, and long-lasting durability, making it an excellent choice for Porsche maintenance, repairs, and restoration projects.
