Special Tools

Ko-ken Tools welcomes customer's inquiries for special tools. New items can be designed and manufactured according to customers requirements.

Impact Socket Quick Release

Save time with the Quick release and Locking system by eliminating the need for the Pin/O-Ring or Retaining Clip. A steel ball locks a socket securely using the hole the Pin or Retaining clip would have used.

PATHFINDER®

The beveled flats of the 6-point opening of the PATHFINDER® socket engage the nut almost immediately. PATHFINDER® sockets are ideal for use with power tools in automatic assembly processes, and multi-spindle application. PATHFINDER allows the tool to easily engage the fastener without the tool being at rest.

Impact Thin Wall Sockets

SURFACE DRIVE

Surface drive sockets are designed to retain contact with the flat sides of a nut to transmit high torque and reduce nut wear. These sockets are ideal for use on polished nuts, aluminum nuts and nuts with worn out points.

2012 Ko-ken Automotive Catalog

The new catalog contains over 125 products, including wrenches, sockets, and specialty tools designed specifically for the automotive repair market.

FLAT DRIVE®

Flat Drive is designed to guarantee a flat surface contact between the socket and the bolt/nut. The Flat contact reduces wear and allows to transmit a higher torque value. The Flat Drive System is also used for the square drive end as well as the hexagonal or bi-hexagonal openings of the socket.
