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.
