square drive screws.

Wikipedia has a nice explanation of the different sizes.  Here's the link:

As far as where to find them, I saw some at HomeDepot.com.

The largest Robertson I have is a #4, a solid black handle.

The yellow is a 0, green is a 1, red is a 2 and 3 is ?.

For really large ones, I have used a tuning lever tip wrench.
