Selecting the right option
Match the 3/8 in square drive to your ratchet or handle, then choose the size that fits the fastener. Choose the deep series when a standard socket will not reach the fastener, for example a nut on a long stud. 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.
