SK Hand Tool 8933 3/8-Inch Drive Deep Impact Socket, 13mm
Sure Grip Drive Design drives the side of the fastener, not the corner, to provide increased strength and avoid rounding of rusted or damaged fasteners. Made in the U.S.A., featuring the Sure Grip hex design, which drives the side of the hex, not the corner. The nose-down design extends the taper as far as possible for improved access over straight wall designs. Coated with a rust-preventative compound that makes them exceptionally resistant to corrosive factors.
