Also note that many "Philips" screws from the Asian market aren't really Philips screws. They are often JIS point screws. They look just like Philips because they are both cross point screws. But JIS screws have a different angle on the point of the driver, and if you use a Philips driver you will strip them quickly. If you use a JIS driver, you can feel the better grip and you suddenly stop stripping screws out.

Another example is that on many servos, the screw that holds the arm on is often JIS.

Unfortunatly JIS drivers are not always easy to find, but if you get a set you'll wonder how you lived with out them.

As for spinners, I usually replace the screw with a hex head anyway, because hex is just easier than any cross point .
