Nut Grip, 1/4” drive, Short, 12 Point.  NUT GRIP® is Ko-ken's special design for non-magnetic nuts/bolts to be held firmly in 6-point sockets and now 12-point sockets. The 12-point design consists of three 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.
