Our 3/8 in drive metric six-point socket with four flat™ sides was designed from the ground up to be part of the most versatile socket family. MILWAUKEE® 3/8 in 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 you with improved, easy-to-read visibility. These deep and standard socket sizes have optimized geometry to reduce bolt rounding and stripping. We back all our 3/8 in drive metric sockets with a lifetime guarantee. Our 3/8 in drive metric socket sizes range from 6 to 19 mm in standard and deep well sockets.
