Remington 700 trigger guard screws

[stephen87]

I'm looking for the screw sizes of a Remington 700 trigger guard. Specifically, the center/smallest one. I have the other two out and realized that the center one is either too small or too big for what I have. SO tomorrow, I get to stop by the hardware store and grab me a hex set with the proper size. Anyone help out on size?
