• SureGrip® Drive Design drives the side of the fastener, not the corner, to provide increased strength and avoid rounding of rusted or damaged fasteners.
• The nose-down design extends the taper as far as possible for improved access over straight wall designs.
• Laser engraved with 3 extra large markings every 120 degrees around the sockets for improved readability.
• Coated with Black Phosphate- a rust-preventative compound that makes them resistant to corrosion
