Milwaukee 3/8" Drive 12 mm Deep Socket

The MILWAUKEE 3/8" Drive 12mm Metric 6-Point Deep Socket with FOUR FLAT Sides was designed from the ground up to be part of the most versatile socket family. The 3/8" drive sockets feature an innovative design with four parallel flat sides, which deter rolling and are wrench-compatible. The metric socket sizes are stamped into the flats providing users with improved, easy-to-read visibility. These deep well sockets have optimized geometry to reduce bolt rounding and stripping. Milwaukee backs their 3/8" drive metric sockets with a lifetime guarantee.
