Ko-ken Tool Company is recognised as one of the leaders in the international tool production industry founded in Japan in 1946. Today over 8000 individual stock items and 4000 special customer items have been produced and inspected according to DIN, ISO and JIS standard by request.
Ko-ken Products are designed and manufactured using the latest technologies such as 3D-CAD, machining centres and computer controlled heat treatment systems in order to deliver the highest quality and most modern designed sockets and accessories.
The Flat drive is designed to guarantee a flat surface contact between the socket and the bolt nut. The Flat contact reduces wear and allows to transmit a higher torque value. The Flat Drive System is also used for the square drive end as well as the hexagonal or bi-hexagonal openings of the socket.
