⚙️ Key Features

• Flange screw with an integral bearing flange
• 0.009 kg
• Supersedes 20459182 and 20497047, catalogued earlier as a hexagon screw and a screw
• Listed for 46 fitments across the D, TD, TAD and MD series

🔌 Function

Clamps the joint while its integral flange spreads the load across the mating face, doing the work a separate washer would otherwise do.

⚠️ Common Signs of Failure

• The screw found loose or backed off at its position
• The joint weeping where the clamping load has been lost
• The flange face marked or dished from previous over-tightening
• A corroded thread that binds or shears on removal
• The head rounded so a socket will no longer grip

🛠️ Service Notes

• Do not add a separate washer under the flange - the flange is the designed bearing face and an extra washer changes how the joint clamps
• A workshop list quoting 20459182 or 20497047 is filled by this number
