The Ko-ken 3/8″ Sq. Dr. Semi-Deep NUT GRIP Socket is a versatile tool that combines secure fastening with a medium-height design. The “Semi-Deep” designation means this socket is taller than standard sockets but not as tall as deep sockets, making it perfect for accessing fasteners in moderately recessed areas. The NUT GRIP feature incorporates a specialized 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 reliable grip, minimizing the risk of dropping or losing fasteners during use. With its semi-deep reach and dependable nut grip system, the Ko-ken Semi-Deep NUT GRIP Socket is an essential tool for both professional mechanics and DIY enthusiasts, offering enhanced accessibility and secure fastening for a variety of tasks.
