Socket End Wrench: 12 mm Socket Size, 6-Point, 8 21/32 in Overall Lg, Metric

Non-sparking fixed-head socket end wrenches contain no ferrous metals, so they resist creating sparks that may ignite materials. This reduces the risk of ignition when using the tools in locations where combustible dust or flammable liquids, gases, or vapors are present. Their fixed head applies more torque than a flex head.
