Need Monitor Stand Screw for HP VH240a

[slopo]

Hello, I have a HP VH240a 23.8-inch monitor that is sitting precariously on the pedestal and has already fallen over on me a couple times. There is a screw hole on the bottom, but I have no screw. Can anytone tell me what size screw I need or how to get a screw from HP?

BTW, I've checked the manual and it just says "Attach the pedestal stand to the base.". No mention of a screw, but it clearly needs one. http://h10032.www1.hp.com/ctg/Manual/c05557046.pdf

It does not have anything called screw from its parts list:

Thanks for the reply. I get that, but I still need a screw. Maybe the screw was pre-installed or supposed to be pre-installed on the pedestal . It's been so long, I don't recall. I don't see a stand/pedestal on the parts list either, so not sure how accurate this part search really is.
