## ⚙️ Key Features

-   0.020 kg
-   88 applications - the widest fitment of the four nuts listed here
-   Covers the D, TAD, TWD and TADH series
-   No thread size published

## 🔌 Function

Clamps a threaded joint by tightening down on a stud or bolt, holding the assembled parts tight against one another.

## ⚠️ Common Signs of Failure

-   Nut loosening in service and the joint weeping or knocking
-   Thread damage that stops the nut running down freely
-   Rounded flats from a worn spanner or socket
-   Seized solid by corrosion on the stud
-   Nut face bedded into the component, leaving a bright pulled ring

## 🛠️ Service Notes

-   Renew any nut that has been run down over a damaged thread
-   Check the stud before refitting - a stud that turns with the nut is coming out of the block and needs attention first
