Having the right size socket makes any job easier. Dependable, high-quality socket sets with wide coverage are always helpful in any toolbox. The Powerbuilt 9 Piece 3/8 Inch Drive SAE 6 Point Deep Socket Set is a useful assortment of 6-point SAE Z-Drive deep sockets. The Z-Drive prevents rounding or fasteners while turning damaged fasters by contacting more of the flat surfaces of nuts and bolts. The sockets are mirror-polished chrome vanadium steel for durability with forged sizing markings that will never wear off. Center holes are punched through the sockets to allow for longer nuts and bolts. The sockets also feature precision chamfered hex faces, allowing easier mating with fasteners. Powerbuilt sockets all meet or exceed ANSI standards. The set includes 3/8-inch drive deep sockets 3/8-inch, 7/16-inch, 1/2-inch, 9/16-inch, 5/8-inch, 1/2-inch, 11/16-inch, 3/4-inch, 3/16-inch, 7/8-inch. Comes with a socket rail storage clip.
