Four Flat Drive Socket 3/8inch Drive Metric Standard 21mm 6 Point

Milwaukee's range of 6-point Sockets with FOUR FLAT™ Sides have been designed from the ground up to be part of the most versatile socket family. Milwaukee® chrome sockets feature an innovative design with four parallel flat sides, which won't roll away when they drop on the floor and are wrench-compatible. The socket sizes are stamped into the flats providing you with improved, easy-to-read visibility. Coming in both deep and standard sizes, each has optimised geometry on the internals to reduce bolt rounding and stripping. All chrome sockets come with a lifetime guarantee.
