Overview
The Klein 2-in-1 Coated Impact Socket, 12-Point, 3/4 and 9/16-in. (66030) is a single-ended impact socket designed for installing and removing pole hardware with an impact wrench.
It carries the two most common pole hardware sizes in one tool and switches between them hands-free. The 12-point design is easy to position and works on square fasteners, and the 1/2-in. drive deep socket reaches pole hardware. A cross-hole design keeps the adapter and socket from separating.
The body is 4140 steel, 3-1/8 in. (79 mm) long, and weighs 0.8 oz. (23 g). It is designed for Klein's 1/2-in. Compact Impact Wrench and other impact tools.
