Our 3/8" drive socket sets with dedicated storage rails have been designed from the ground up to be part of the most versatile socket family. MILWAUKEE® sockets feature an innovative design with FOUR FLAT™ parallel flat sides which deter rolling on surfaces and are wrench-compatible. The socket sizes are stamped into the flats providing you with improved, easy-to-read visibility, while the fastener attachement face has optimised geometry to increase torque and reduce bolt rounding.Our dedicated storage rails offers a simple and convenient way to store your sockets.
