🔌 Function

⚠️ Common Signs of Failure

• Key spinning in a rounded or burred socket
• Screw backing out and the joint gaping or weeping
• Galling or seizure when the screw is wound out
• Shank stretched or the thread visibly necked
• Component face fretted or bruised around the screw hole

🛠️ Service Notes

• The 20 mm screw is 984298 - measure the screw you removed, since the published weights do not rise with length across this pair
• Clean the socket out fully before applying the key; grit in the drive is what rounds these heads
