Product Information
Driveshaft Bolt, M10 X 50.
The OE Match Driveshaft Bolt, M10 x 50 is a high-strength replacement fastener designed to securely attach the driveshaft (CV joint) assembly to the transmission or wheel hub flange. Manufactured to OE specifications for fit, strength and durability, this precision-engineered bolt is designed to withstand the high torque loads, vibration and stresses generated by the drivetrain during normal and performance driving conditions.

As a critical drivetrain fastening component, the driveshaft bolt helps maintain a secure connection between rotating driveline components, ensuring reliable power transfer from the gearbox to the wheels. It is an essential replacement item during driveshaft servicing, CV joint replacement or drivetrain repairs.

What This Product Does:
  • Secures the driveshaft and CV joint assembly to the mating flange.
  • Maintains a safe and reliable drivetrain connection.
  • Allows efficient transfer of engine power to the wheels.
  • Helps ensure proper alignment of driveshaft components.
  • Resists loosening under vibration and torque loads.
  • Supports safe vehicle operation and drivetrain reliability.

Symptoms Of Wear Or Failure:
  • Clicking or knocking noises from the drivetrain.
  • Excessive movement at the CV joint connection.
  • Loose driveshaft mounting hardware.
  • Vibration during acceleration or driving.
  • Visible corrosion or damage to bolt threads.
  • Rounded or damaged bolt heads.
  • Oil or grease leakage caused by drivetrain movement.
  • Risk of driveshaft separation in severe cases.

Why Replacement Matters:

  • Driveshaft bolts are subjected to constant rotational forces, torque loads, vibration and environmental exposure. Over time, bolts can stretch, corrode, suffer thread damage or lose their clamping force, particularly if reused after removal or incorrectly torqued during installation.
  • A compromised driveshaft bolt can allow movement between drivetrain components, potentially leading to CV joint wear, vibration, driveline noise and reduced vehicle safety. In extreme cases, fastener failure can result in driveshaft detachment and significant drivetrain damage.
  • Replacing worn, damaged or removed driveshaft bolts with OE Match replacements helps maintain proper clamping force, secure drivetrain operation and long-term reliability. Using the correct specification fasteners is essential when carrying out CV joint, driveshaft or transmission service work.
