"common driver" Robertson head screws are common here. Don't know why they never caught on in the States.

You are less likely to have to resort to some sort of alternate extraction device with Robertson head screws. They are way better than Phillips or slot heads in transferring torque from the screwdriver to the screw. In my opinion they are better in all applications except for assembly line work, where speed of assembly is the overriding concern, and where the engineers don't care if it is later difficult to remove them. The only thing I would do is make sure that they are stainless or bronze, and check them once in a while if you are concerned that they will fill up with dirt. That is not something that is likely to happen quickly. Virtually every screw used to fasten anything that is connected to the hull of my boat has required re-tightening at some time. There must be a lot of flexing going on that is not obvious when actually sailing the boat.

Looking at the CS 30 I had a really tough time getting under the floorboards - the Robertson head screws were full of dirt an it was very difficult to get many of the screws out. I had to use a little dental tool I'd brought with me to gouge the dirt out of each hole to make space for the screwdriver head. I'd hate to be trying to do that if I was in an emergency that necessitated access! Any better suggestions? Would you just go with a slot screw? Any better ideas - still seems to me you might be frantically trying to find a problem and the sheer number of screws could be overwhelming. Mark
