* JIS means Japanese Industrial Standards. This standard is applied for Japanese Standards screws, and is mainly used in Japanese-made cars, motorcycles, home appliances, etc. The tips of VESSEL screwdrivers and bits are manufactured in accordance with JIS. In addition, VESSEL has developed its own in-house standards to achieve even higher precision and quality tips.
VESSEL JISDRIVE was developed with the concept that the 4 sides of the tip should fit the screw evenly, allowing you to turn screws with confidence. As a result, VESSEL tips can fit any standard screws and transmit force without loss.
