Our SHOCKWAVE Impact Duty™ 1/2" Drive Metric Deep 6 Point Socket Sets feature the boldest, longest-lasting markings and extreme impact durability in high torque applications. The stamped and ink-filled size marking enables you to select the right socket every time throughout the life of the socket. Our sockets are engineered with high strength forged steel for optimized performance in heavy-duty applications. The non-slip hex geometry prevents fastener rounding, and a dual-hole design and ring groove allow for easy socket attachment and removal. The customizable Socket Rail comes with removeable end caps to add or take off socket clips for optimal storage. All MILWAUKEE® SHOCKWAVE Impact Duty™ Sockets are backed by a Lifetime Guarantee and meet ASME industry standards.
