Clutch Head Screw Removal

Removing clutch head screws can sometimes be challenging due to their unique design. Clutch-head screws have a specialized head with a recessed center and two small pins, requiring a specific tool to remove them.

Follow these steps to remove the clutch head screws:

Tools Needed:

  • Clutch head screwdriver or clutch head screw removal tool
  • Pliers (optional)
  • Safety glasses


  1. Prepare the Area: Ensure you’re working in a well-lit and well-ventilated space. Put on safety glasses to protect your eyes from any debris.
  2. Choose the Right Tool: Obtain a clutch head screwdriver or a clutch head screw removal tool that matches the size of the clutch head screw you intend to remove. These tools have a unique shape that fits into the recessed center of the screw head.
  3. Position the Tool: Insert the clutch head screwdriver or removal tool into the recessed center of the clutch head screw. Make sure the tool’s pins align with the pins on the screw head.
  4. Apply Steady Pressure: Hold the tool firmly and apply downward pressure to engage the pins of the tool with the pins on the screw head. Make sure the tool is seated securely in the screw head to prevent slipping.
  5. Turn counterclockwise: While maintaining pressure on the tool, turn it counterclockwise (left) to loosen the clutch head screw. Clutch-head screws are designed to resist tampering, so you might encounter resistance initially.
  6. Use Pliers (If Necessary): If the clutch head screw is particularly tight or stubborn, you can use pliers to grip the shaft of the screwdriver tool for added torque while turning. Make sure you grip it securely to avoid slipping and damaging the screw head.
  7. Continue Turning: Keep turning counterclockwise until the clutch head screw is fully loosened and can be removed from its position.
  8. Inspect and Replace: Once the screw is removed, inspect it for any signs of wear or damage. If necessary, replace it with a new clutch head screw.
