Our nut grip sockets are unique to Ko-ken and truly a revolutionary way of approaching this type of socket. Our fastener holds nuts and bolts in place without the use of magnets. Our system is built with a coil spring and ball bearings on opposing flats. When a nut or bolt is in the socket the ball bearing pushes out on the springs holding the nut/bolt in place.
Our nut grip sockets can completely change a mechanic's work ethic. If you lose a nut or bolt inside and engine a lot of time you must take the entire engine apart to find the bolt. With nut grip sockets that dilemma is completely eradicated.
TORX® is recognized as one of the three most efficient fastening systems because of their ability to transfer greater torque, reduce load and virtually eliminate tool slippage.
