Does anyone by chance know what size screws/bolts are used for securing small (1.5" x 1.5") Board cameras? They are smaller than 4-40. I am thinking 2-56 but before I order them I want to be certain.

If you have a pair of calipers you could take a measurement of the diameter of the mounting holes, then compare to the diameter of a 2-56 screw. I bet a 2-56 would fit if it's too small for a 4-40. McMaster Carr here you come!
Great idea!!!! I can't believe that slipped my mind. Now I just need to find my calipers. I think Lowe's carries Nylon screws that small so I may just go that route.

Ace usually carries nylon hardware, but I notice the selection varies store to store.
I used to be able to get a variety of 4-40 hardware from the local Home Depot, but the last time I was in there they didn't have anything smaller than 6-32. I guess there just wasn't enough sales volume.

The major diameter of a numbered thread (e.g. 6-32) is given by D=0.013*N+0.060 so a #6 has a major diameter of 0.138 in.
