Features and Benefits:

• Nut Grip
• Universal
• Z-Series



The Ko-ken 3/8" Sq. Dr Universal Z-Series NUT GRIP® Socket is an advanced tool designed for maximum flexibility and strength in fastening tasks. The "universal" designation refers to its innovative dual hexahedron mechanism, which connects in the middle of the socket body, allowing it to swivel up to 50 degrees in all directions. This unique design not only enhances accessibility in tight or awkward spaces but also disperses the torque load across the entire body of the tool, resulting in a higher torque tolerance compared to other universal sockets and joints. The NUT GRIP® feature includes a system with coil springs and ball bearings on opposing flats. When a nut or bolt is inserted, the ball bearings push outward against the springs, securely holding the fastener in place. This ensures a firm grip, reducing the risk of dropping nuts or bolts during use. The combination of a robust, torque-dispersing universal mechanism and the reliable nut grip system makes the Ko-ken Universal Z-Series NUT GRIP® Socket an exceptional choice for both professional mechanics and DIY enthusiasts.
