Some have been asking why we use small cross threaded stainless steel screws instead of hex head. Hex would be easier to screw in, thats for sure. But there are two reasons we stick with the cross head. First, they are small and black, so they are not noticible. Second, they are harder to screw in, so that means its less likely to strip out the plastic housing.
In the end they make a nicer installation. And being stainless, they will not rust.
