The sockets are coated with a rust-preventative compound, which makes them exceptionally resistant to corrosive factors. In addition to the rust-preventative coating, the sockets are laser engraved every 120° with extra-large markings for improved readability. All the SK impact sockets feature the SK's SureGrip® hex design, which drives the side of the hex, not the corner.

This not only providesincreased strength, but also avoids the rounding of rusted or damagedfasteners, which can occur when using a sharp cornered hex tool. 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.
