111 Action Screw Size

So I've been thinking about replacing the plastic trigger guard on my 111 with a metal one and while looking around the interwebs I noticed that there seems to be a couple different sizes stated for the action screws. Some say it's 1/4-28, another says 5-23" there was another different measurement that I noticed but I forgot what is was. So the question is, what is the correct size for the action screws on a savage 111?

1/4-28 is the correct size for action screw, 5/32 is the hex wrench size.

Thanks
