Milwaukee 3/8 in. Drive 13mm Metric 6-Point Socket

The Milwaukee 3/8 in. drive 13mm metric 6-point socket was designed from the ground to be part of the most versatile socket family. The innovative socket design has four parallel flat sides, which deter rolling and are wrench-compatible. Socket sizes are stamped into the flats for improved easy-to-read visibility. Optimized socket geometry helps reduce bolt rounding and stripping.
