Selecting the right option

Choose the hex size to match the screw, and use the bit in an impact bit holder that takes a 16 mm input hex. A catalogue footnote says the items it marks have a larger output size than the 16 mm input hex drive, so their maximum output torque rating is less than standards. Check the marked sizes in the Ko-ken catalogue before using at high torque. (manufacturer-stated) The catalogue's safety notes say to select impact sockets only for electric or air impact wrenches, to wear safety goggles when using nut runners or impact wrenches, never to substitute a hand socket for an impact socket, and to replace sockets with cracked walls, battered points or other marks of wear.
