The 1099-9 thumbnut is a screw that secures the trough cover to the distributor trough. The cover shields the distributor trough, which disperses water onto the humidifier pad. If the trough cover needs to be replaced, it is a good idea to also replace the thumbnuts. 

Also known as part 7043. Replaces 12408
