3/8 Inch Drive x 1/2 Inch 12-Point Socket

TEKTON 3/8 inch drive 12-point sockets are an exact fit for double hex fasteners and also work with hex and square shapes. They’re designed to grip the sides and not the corners of the fastener heads, which prevents round-off. The large, die-stamped markings are permanently impressed into the material and optimized for readability.
