Continued advancements in engine designs and structures are producing engines that are more
complex and compact.
Work environments are being transformed to cater towards increased demands on auto mechanics.
We at Ko-ken TOOL CO., LTD., specialists in socket wrench manufacturing, have been committed to the development of automotive tools that are more suitable by pouring in our passion for perfecting
hand tools and utilizing our experience obtained through over half a century of manufacturing to
create the Z series.
“Z” stands for “zeal”. Through their unequaled performance, Z-Series tools are certain to become the
mechanic’s new standard for the next generation of automotive tools.
The designs were thoroughly reviewed to produce the
Z-series.
All items in this series are now more compact.
Foregoing standards, radical design concepts have
been implemented in producing the Z-series which
enables maximum potential in all professional mechanics.
Movement at the joint between a socket and a ratchet
or other drive accessory has been accepted as unavoidable.
To reduce this movement, we thoroughly reviewed dimensional accuracy of all the joint parts of Z-Series,
and any movement in the rotating direction has now
been minimized through production technologies.
The new Ball Holding system was installed. Any movement in the connecting direction has been reduced by a mechanism that pulls the parts together.
This ratchet handle has a new mechanism for enhanced usability.
This Ratchet has incredibly light turning torque that enables working on loosely tightened bolts.
With the compact head and balanced design, the Z-Series ratchet has evolved into what can be called the “ideal ratchet handle”.
Innovative new locking mechanism is installed. This new mechanism achieved both of locking a socket and also unique feature of Z-series pulls parts together for tight connection.
The length and diameter of sockets have been significantly reduced.
Ideal for working in confined and tight areas.
Foregoing the ISO and DIN standards, radical design concepts have been implemented in producing the Z-series which enables maximum potential in all professional mechanics.
