This metric set of Milwaukee impact sockets is of high quality and comes with large stamped markings for socket size and bright white ink to fill the markings. The sockets are manufactured from forged high torque impact steel for durability and include a non-slip hex geometry to reduce damage to the socket and rounding of the fastener. The sockets are also well embossed and come with extra goodies like an extension and a small hex adapter. Overall, this is a great product that is highly recommended.
