1/4" flathead driver bit should be compatible with most camera tie-down screws. Printed tip dimensions should come out 11.1mm x 1.8mm and are easily sanded down if too thick.
More adaptable than the standard stubby flathead allowing access to those hard to reach capture screws (I'm looking at you Zacuto!).
Great camera assistants tool!
