11 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. Flare nut crowfoot wrenches are designed for use on soft fittings such as brass and aluminum. 11 Piece 3/8" Drive Metric Flare Nut Crowfoot Wrench Set
