🔌 Function

Clamps two components together, its integral flange spreading the load across the joint face in place of a separate washer.

⚠️ Common Signs of Failure

• Screw working loose, with the joint face fretting or the paint cracking around the head
• Thread picked up, galled or stripped on removal
• Head corroded or its drive rounded so a socket slips
• Thread binding part way down, showing the screw has stretched
• Flange face dished or distorted

🛠️ Service Notes

• Five earlier numbers now come through as this one screw, so an old parts list may point at any of them
• It shares its 0.045 kg listing with the 40 mm screw 984816, so weight will not tell them apart. Order by the marked length: 984815 is 30 mm, 984816 is 40 mm, this one is 50 mm, 984817 is 60 mm and 984818 is 80 mm
