Selecting the right option
Match the 3/8 in square drive to your ratchet or handle, then choose the hex size that fits the fastener. The catalogue's safety notes say to select impact sockets only for electric or air impact wrenches and not to substitute hand sockets for impact sockets; this series is listed in the hand sockets section of the catalogue.
