🔌 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
