## ⚙️ Key Features

-   0.03 kg
-   Supersedes 956586
-   21 applications across six engine families
-   Driven with a hexagon key
-   8 used per assembly

## 🔌 Function

Clamps the joint and is driven with a hexagon key, so it can be tightened in confined spaces.

## ⚠️ Common Signs of Failure

-   Hexagon socket rounded out so the key will not bite
-   Head corroded or seized in the casting
-   Thread stripped or pulled
-   Screw working loose in service

## 🛠️ 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
