KK Impact Tools

KO-KEN impact sockets are designed for use with powered impact wrenches. The combination of an impact wrench and impact socket can deliver greater torque to the head of a fastener than can be achieved with a manual wrench.

Impact sockets can be attached or detached on the LOCKING ADAPTOR for safety just by sliding the holder rather than using a pin and an O-ring. It can reduce the time to change a socket, especially when you need to use a variety of socket sizes.
