1/4" Sq. Drive Z-Series 6 Point SAE Socket - 7/16"

The Ko-ken Z-Series represents the new standard for professional automotive mechanics, combining a compact profile with high performance. Engineered for tight and hard-to-reach spaces, Z-Series sockets feature a thin-wall, low-profile design without compromising strength or durability. Their innovative interior geometry delivers a tighter fit between the socket, drive, and ball bearing—minimizing movement and ensuring a more secure, stable connection. With precision tolerances and superior build quality, the Z-Series sets a new benchmark for accessibility, control, and reliability in modern automotive work.
