Fog Light Screws

[Chillin]

Does anyone know what size screws are used to attach my foglights to the bezels/bumpers. I called the dealer and they couldnt give me a size, just a cost of $2.14 each. I'm sure I could just go to HomeDepot or my local screw and bolt store for them for alot cheaper, just need the size.

My screws in the factory kit were stripped so I went and bought some allen head screws, washers and nylock nuts to mount them.
The size they come with is a 4mm x 25mm.
