⚠️ Common Signs of Failure

• Hexagon flats rounded by a slipping socket
• Thread stripped or seized in the tapped hole
• Screw stretched or snapped at the thread run-out

🛠️ Service Notes

• Important - many of the numbers it replaces are also replaced by other current screws: 22257075 maps to 984733, 984740 and 984752; 3589243 maps to 984725; 22496578 maps to 984736; and 21790519, 23065849, 23398215, 23706466 and 78546572 all map to 984733 as well, so an order against one of those old numbers may need two or more current parts
• Order by the measured thread and length, not by weight - this screw is published at 0.045 kg at 20 mm while the 30 mm screw 984736 is published at 0.016 kg, so the figures do not track length at all
• No thread size is published for this screw, so measure the one you removed before ordering
