KK Z-Series

WHAT IS THE Z-SERIES?

Koken Z-Series is designed for lower profile applications in difficult to get to locations. Recent year garage tools (automobile maintenance tools) are requested to respond working at narrow space of engine rooms.

There is severe situation that the standard of socket wrenches can be made only a small change, but cannot be made substantial one because of many restrictions and historical background. In this situation, we believe that compact size sockets will become standard lines which will be accepted by mechanics, and develop the mechanic standard sockets.

As an expert maker, we have been manufacturing socket wrenches for half century, and give our know-how and enthusiasm on them. Here we provide Z-series as next generation mechanic standard of socket wrenches.
