⚙️ Key Features

• 0.059 kg
• 191 applications across six engine families
• Flanged face bears directly on the joint
• Self-locking type

🔌 Function

Clamps a bolted joint and resists loosening under vibration, with an integral flanged face that spreads the load over the component instead of a separate washer.

⚠️ Common Signs of Failure

• Joint working loose or the nut backing off between services
• Flange face distorted, dished or bitten into the component
• Thread stripped or galled when the nut is removed
• Locking action gone, so the nut spins freely down the thread

🛠️ Service Notes

• Self-locking nuts lose their grip once disturbed, so fit a new one rather than reusing the old
• Check the stud or bolt thread for pickup before refitting

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
