## 🔌 Function

Secures the fastener against vibration, holding its own tension so the joint does not back off.

## ⚠️ Common Signs of Failure

-   Nut running down the thread with no resistance
-   Nut backed off after a period of vibration
-   Corners rounded by a slipping spanner
-   Corrosion seizing the nut to the thread

## 🛠️ Service Notes

-   Fit a new lock nut every time the joint is disturbed — a reused one has lost most of its locking effect
-   Check the stud or screw thread for damage before fitting
