RBS50Y Mounting screw questions

Sorry for the strange question but .... 

We have a RBS50Y outdoor Router that we have been using on the stand for a while.  We recently had a Gazebo built and I would now like to mount the Router to the Gazebo but I can't find the original screws.  I realize any wood screws will do but the two "Tourxe" screws that hold the wall mount bracket lock are going to be a little tricker to find.  I don't see the size anywhere in the manual (Screw #10).  Does anyone have them to sell?  (or know the size?) I'd be happy to pay and have them mailed rather than sitting in a hardware store for 45 minutes trying different sizes.
