KennedyPro 3/8″ Bi-Hexagonal Standard & Deep Sockets, Imperial

Bi-Hexagon Sockets
12 point – side drive design gives a higher torque than normal sockets, grip worn nuts and will not round off existing nuts. All have a ball-retaining groove on each face of the square drive, which ensures a positive fit with accessories. Require only a one-twelfth turn to engage the next point of the socket.
