Nut Grip, Chrome Hand Socket Driver.NUT GRIP® is Ko-ken’s special design for non-magnetic nuts/bolts to be held firmly in a 6-point socket.The design consists of two balls held in place by a spring steel ring. 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 bearings push out on the springs holding the nut/bolt in place.
