⚙️ Key Features

• Hexagon socket head

🔌 Function

Clamps the assembly together through a socket head that can be tightened where there is no room for a spanner.

⚠️ Common Signs of Failure

• Screw found loose or backed out
• Socket rounded so a key will no longer grip
• Thread corroded, picked up or stripped
• Screw stretched or snapped in the hole
• Rust weeping from around the head

🛠️ Service Notes

• Length is what separates this from its siblings, with 851859 at 140 mm and 851860 at 40 mm, so measure before ordering
• Clean the socket out before inserting the key, since packed dirt is the usual reason a socket head rounds off
