## 🔌 Function

Clamps two components together, its integral flange spreading the load across the joint face in place of a separate washer.

## ⚠️ Common Signs of Failure

-   Screw working loose, with the joint face fretting or the paint cracking around the head
-   Thread picked up, galled or stripped on removal
-   Head corroded or its drive rounded so a socket slips
-   Thread binding part way down, showing the screw has stretched
-   Flange face dished or distorted

## 🛠️ Service Notes

-   Length is the deciding detail in this run of screws, so order by the marked length rather than by weight
-   The flange does the work of a washer, so the screw is fitted directly against the component face
