## 🔌 Function

Locates its component on the plain shoulder while the threaded end takes the clamp load, so the component is positioned by the shoulder rather than by the thread.

## ⚠️ Common Signs of Failure

-   Component able to move or rattle on its mounting
-   Shoulder worn, stepped or picked up where the component runs on it
-   Screw working loose in service
-   Thread pulled or stripped on tightening

## 🛠️ Service Notes

-   Do not substitute a plain screw — the shoulder sets the position and a plain screw will clamp the component solid or leave it slack
