I received some 3-48 slotted Binding Head machine screws from McMaster-Carr (Part # 91793A094) today for use with the 2m long µrail. The slot width on the longer rail is tiny bit wider than the short low power µrail and while the 2-56 binding head screws will work they have little margin. These 3-48 screws are a perfect fit in the slot. The 2-56 nylon bushings I have can be tapped to fit the larger screw. This looks like a winning combination for hefty mid-power rockets.
