## ⚙️ Key Features

-   Captive washer assembled to the screw
-   0.016 kg
-   50 applications on D series engines
-   Supersedes 985806

## 🔌 Function

Clamps the joint with its washer held captive on the screw, so the two go on together and the washer cannot be left off.

## ⚠️ Common Signs of Failure

-   Screw working loose, with the joint face fretting around the head
-   Washer seized, distorted or no longer turning freely on the screw
-   Thread picked up, galled or stripped on removal
-   Head corroded or its drive rounded so a tool slips

## 🛠️ Service Notes

-   The washer is captive, so do not add a second one under the head. If the washer has seized to the screw, renew the pair rather than trying to free it
-   The number it replaces was listed as a hexagon screw, so an older joint may have had a loose washer that this screw now carries with it
