## ⚙️ Key Features

-   0.016 kg
-   26 applications across the TAD, D and TADH series
-   3 used per assembly

## 🔌 Function

Clamps two components together where a socket drive is needed because there is no room to swing a spanner.

## ⚠️ Common Signs of Failure

-   Joint working loose or weeping at the face
-   Socket recess rounded out by a worn key
-   Thread stripped or galled on removal
-   Head cracked or the corners of the socket broken away

## 🛠️ 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
