An example of Ko-ken design excellence and manufacturing quality. The compact design is 5 - 9mm shorter making them ideal for working in tight areas. Manufacturing tolerances of the Hexagon opening & Square drive are precisely controlled. The tight tolerances and ball mechanism provide the most secure connection between Socket and Handle in the Industry.

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® sockets are ideal for use with power tools in automatic assembly processes, and multi-spindle application.
