## ⚙️ Key Features

-   43 applications across TAD, D and TWD
-   Hexagon head
-   Quantity varies by assembly, most commonly 8

## 🔌 Function

Clamps a substantial joint together, the hexagon head taking spanner or socket torque.

## ⚠️ Common Signs of Failure

-   Screw found slack on a loaded joint
-   Flats rounded or the head burred
-   Thread stretched, necked or galled
-   Joint fretting or weeping where tension has dropped
-   Corrosion seizing the screw in its hole

## 🛠️ Service Notes

-   994490 is published at 0.174 kg, close enough that weight will not separate the two, and covers only two applications against this one's forty-three - order by part number
-   Use a six-point socket; an open spanner will round the flats on a seized screw of this size
