NUT GRIP, 1/2” DRIVE, STANDARD LENGTH, CHROME HAND SOCKETS. 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.
