Features and Benefits:
3/8" square drive, SAE, Standard Length, Flat-Drive, 6-Point Socket Set in 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, and 3/4 inch. Ko-ken Flat Drive sockets are engineered to ensure a flat surface contact between the socket and the bolt/nut. This design minimizes wear and enables the transmission of higher torque values. The flat drive system is implemented not only for the square drive end but also for the hexagonal or bi-hexagonal openings of the socket.
