5-pc 1/4" Square Drive Z-Series Universal Nut Grip Sockets, No. RS2441MZ/5

The 5-pc 1/4" Square Drive Z-Series Universal Nut Grip Socket Set, No. RS2441MZ/5, from Ko-Ken, is designed 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. Ko-Ken's universal joints are connected with mutually engaged hexahedrons. This connection disperses the load across the whole outer circumference. The same durability is obtained with this design in comparison to the pin-type.
