## 🔌 Function

Clamps two components together, its integral flange acting as a built-in washer to spread the load across the joint face.

## ⚠️ Common Signs of Failure

-   Joint weeping or working loose in service
-   Flange under the head dished or bitten into the mating face
-   Thread stretched, galled or picked up
-   Screw corroded into place so it shears rather than releases
-   Drive in the head rounded off

## 🛠️ Service Notes

-   Two grams separate this from screw 23025285 across the same engines, so order strictly by part number
-   Do not substitute a plain bolt and washer - the flange form sets the bearing area
