The basic performance of socket wrenches is thoroughly pursued throughout the series.
The standard socket is shorter/thinner, the ratchet handle is smaller, the gear is finer, etc., and the "Mechanical Standard" considered by Ko-ken is injected into all products.
In addition, by thoroughly managing the accuracy at a higher level, which is not restricted by the standards, we have achieved a superior sense of use.

 

Improvement of accuracy of joints
(Reduction of rattling)
The dimensional accuracy of the concave side of socket wrenches bonded with square concavities and convexities was sought.
Since the clearance between joints inevitably triggers when the receptacles conform to the standard for insertion angles of general-purpose socket wrenches specified in ISO/DIN, etc., the square concave side is brought closer to the limit of the two-sided width on the convex side, thereby reducing the stickiness of the joints.

 

Adoption of new ball dimples
The socket wrenches are held together by steel balls and springs embedded in square convex

sides.
The ball dimple shape provided in the concave side receiving the holding is newly developed, and it succeeds in eliciting the action of attracting the joined members to each other.
Together with the improvement in the accuracy of the joints, excellent jointability has been

realized.
