100% made in the U.S.A. featuring SKs 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. SKs smooth collar design protects the users hand while in use by preventing the pin from working loose. These new SK sockets are coated with a rust-preventative compound which makes them exceptionally resistant to corrosive factors. In addition to the rust-preventative coating the SK sockets are laser engraved with extra-large markings for improved readability.
