Selecting the right option
Match the square drive to your sockets and handle, and choose the length for the reach you need. The catalogue notes that using several short extensions in place of one correctly sized bar should be avoided. 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.
