5 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, while providing long life and maximum corrosion resistance. The SureGrip® wrenching design drives the side of the hex of the fastener, not the corner, to increase torque and avoid edge breakage, especially on rusted or damaged fasteners. Feature 15° offset heads on both ends to help you work near firewalls, engines, wheels and other restricted areas.
