6 piece set is 100% made in the U.S.A., featuring SK's patented SureGrip hex design, which drives the side of the hex, not the corner. Extra recess depth and a 30 degree flex angle allow for improved access. SK's smooth collar design protects the user's hand while in use by preventing the pin from working loose.
