⚙️ 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
