Having the right tool for the job always makes things easier, and it's no exception with the MX-5. Although the screw heads may look like regular Phillips head screws, a normal screwdriver never seems to fit correctly. This is all down to the screws actually being JIS (Japanese Industry Standard) screws, a slightly different size and shape to normal Phillips head screws, meaning any screws you may find too tight on your MX-5 will inevitably end up being ruined because of this. Using a JIS screwdriver ensures this is a thing of the past, with the perfect fit every time. These small end bit tips will fit into most universal screwdriver receivers.
