## ⚙️ 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
