Q:

Screws for HP 2159M Monitor Base

Can anyone help me with what type/size screws an HP Pavilion 2159m monitor uses for its base? 
We moved to a new house a few weeks ago, and I disassembled the monitor base while packing, but misplaced the mounting screws. Now I want to put the monitor back together, but I realized I have no mounting screws so I will need to buy new ones. 
I tried searching online for this info, but couldn't find anything. The below image  - from HP's support page for End-of-life disassembly - shows what screws I am talking about.

A:

Your display mount is VESA (MIS-D) 4-hole 100 mm x 100 mm as mentioned in the link you've provided in your question. This specific type of mount uses M4 type screws meaning the hole depth is 10mm. You can get this type of screws on eBay or ask in a local computer hardware shop (they usually have plenty of those laying around).
