13 piece set is made in the U.S.A., featuring SK's high polish SuperKrome finish, which protects the tools from the harsh working environments found in today's workplace. All sockets feature SK's patented SureGrip hex design, which drives the side of the fastener, not the corner, to avoid edge breakage which can occur on rusted or damaged fasteners when a traditional straight cornered hex tool is used.
