SK 84420 20 Pc. 3/4" Dr. 6 pt. Standard SAE Impact Socket Set

20 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. This not only provides increased strength, but also avoids the rounding of rusted or damaged fasteners, which can occur when using a sharp cornered hex tool. Improved black coating retains more rust preventative compound than black oxide. 5/8'', 3/4'', 13/16'', 7/8'', 15/16'', 1'', 1 1/16'', 1 1/8'', 1 1/4'', 1 5/16'', 1 3/8'', 1 7/16'', 1 1/2'', 1 5/8'', 1 11/16'', 1 3/4'', 1 13/16'', 1 7/8'', 1 15/16'', 2'' Sockets.
