Hi people,

For a school we have received some free monitors, but not all monitor stands had enough screws in them, probably gone missing somewhere. They need to go into the back of the stands for HP Compaq LA2205wg monitors.
What I'm looking for seems to be M4 x 10mm black oxide screws. Does anyone knows who sells them? Pretty hard time getting them, visited 5 stores, none had them (PB Tech, Bunnings, Jaycar, Mitre 10).

They look very similar to this.

The bottom of the head should be flat I think, top is sort of dome (button?) shaped.

They go into what is apparently called 100 mm VESA mount screw holes.

Any pointers much appreciated!
