2400MZ, 3400MZ and 4400MZ are designed 5-14mm shorter than standard 2400M, 3400M and 4400M. Ideal for working in confined and tight areas.
Ko-ken standard sockets are manufactured according to DIN/ISO standards. The tolerances of Z-Series sockets are precisely controlled to achieve a more positive fit between bolt and socket.
Manufacturing tolerance of Male and Female Square are precisely controlled to achieve a more secure fit between Socket and Handle.
Original Ball Holding system is applied on Z-series. This mechanism gives secure connection between Socket and Handle.
Smaller head with 36 tooth gear and light ratchet movement allow working in narrow space and confined areas.
