Selecting the right option
Match the 1/4 in square drive to your ratchet or handle, then choose the size that fits the fastener. The catalogue prints one dimension table for the 6-point and 12-point series (2400A and 2405A), so the lengths and weights shown here are the figures printed for both. (manufacturer-stated) 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.
