## 🔌 Function

Secures engine components together, with the flanged head providing a wide bearing surface that maintains clamping force and resists loosening under vibration. Correct torque and condition of this fastener are essential to joint sealing and component alignment.

## ⚠️ Common Signs of Failure

-   Thread damage, galling or stripped threads preventing correct torque
-   Corrosion or seizing that makes removal difficult and weakens the shank
-   Stretched or snapped screw following over-torquing or repeated re-use
-   Loss of clamping load showing as leaks, weeping gaskets or component movement
-   Deformed or worn flange face no longer seating flat against the joint

## 🛠️ Service Notes

-   This is a critical connecting-rod fastener: follow the exact Volvo Penta torque/angle, length and reuse procedure for the engine serial number.
-   Twelve screws are used on documented six-cylinder crank mechanisms; replace as a complete matched set when required.
