2-in-1 Socket 5/8 x 7/16-Inch (307511P)
by Klein Tools 66012
Single-ended impact socket with hands-free adjustment between 5/8-Inch and 7/16-Inch hex sizes. Deep socket with a 1/2-Inch drive is great for general electrical and construction work. The high-torque, 12-Point design is easier to position and works with square fasteners.
