🔌 Function

Clamps a bolted joint under tension with an integral flange under the head, removing the need for a separate washer.

⚠️ Common Signs of Failure

• Screw slack or the component moving on its mounting
• Flange bent, cracked or bedded into the face
• Thread stripped, picked up or seized
• Head rounded so a socket will not grip
• Corrosion around the head and under the flange

🛠️ Service Notes

• Important - the old number 21699972 is also replaced by the fan guard screw 984739 and by 984754, and 22072117 is also replaced by 984739, so an order against either number may need more than this screw alone
• No thread size is published for this screw, so measure the one you removed - the run around it is M10, but that is not stated for this number
