⚙️ Key Features

• For Duoprop
• 0.023 kg
• 29 applications on D-series engines
• Self-locking thread form
• Quantity varies by assembly, most commonly one

🔌 Function

Clamps a threaded joint and resists loosening under vibration without needing a separate locking washer.

⚠️ Common Signs of Failure

• Joint backing off, with the assembly it holds moving
• Nut running on with no drag, so the lock is spent
• Flats rounded by a slipping spanner
• Thread stripped, cross-threaded or picked up
• Corrosion and salt seizing the nut in place

🛠️ Service Notes

• This is the Duoprop nut of the group, so check the drive you are working on before ordering — lock nut 60115071 at 0.016 kg covers a very similar 28 D-series applications
• Propeller and drive fastenings must be renewed rather than re-used and torqued to the manual figure, since a nut that comes loose afloat loses the propeller

📦 Condition

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