Koken have been supplying sockets & accessories into New Zealand for well over 50 years; becoming the first country to import Koken Tools way back in 1957, some 11 years after the company was formed in Japan by Mr Soichiro Yamashita.

Since then Koken have established themselves as the leading supplier of sockets & accessories, boasting the widest range available including specialty items not available in other brands.
An example of this is the recently added long series Torx Plus IP55 Bit Socket required to remove a Subaru Flywheel - a recognised challenge for mechanics before now.
- The Problem - The bolts are slightly off centre making it almost impossible to get access the bolt head
- The Solution - Koken increased the overall length of the Torx Plus Bit socket to 100mm.
- The Result - The easy access and removal of the flywheel bolts - Problem Solved!
