The high precision black point cross-point tips fit “JIS” (Japanese Industrial Standard) and standard screw heads perfectly. This ensures a correct fit for fastening and helps prevent cam-outs. Therefore, these VESSEL drivers are universal so they can be used as a conventional screwdriver, BUT it has the extra feature of fitting JIS screws
