## 🔌 Function

Clamps a joint together on the engine or drive, holding the assembly in position and carrying the load across the joint face.

## ⚠️ Common Signs of Failure

-   Rounded or chewed hex socket that a key will no longer grip
-   Screw that will not hold torque, or one that works loose on a vibrating assembly
-   Corroded, galled or stretched thread on removal, or a head that shears while being undone
-   A joint that weeps or leaks because a fastener has lost its clamp load

## 🛠️ Service Notes

-   Use a hex key or bit that fills the socket fully and is not rounded off — a sloppy tool fit is what ruins these heads
-   Clean paint, sealant and dirt out of the socket before engaging the tool, and check the threads and the mating face are clean and dry
-   Tighten to the figure and sequence given in the workshop manual for the assembly, rather than by feel — socket screws are often used where clamp load matters and access is poor
-   Renew any screw whose socket is damaged, and refit with thread-locking compound only where the manual for that assembly calls for it
-   Start every screw by hand so it picks up the thread square, particularly into aluminium housings where a cross-threaded start ruins the casting
