Our SHOCKWAVE Impact Duty™ 1/2" Drive 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. These 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. All MILWAUKEE® SHOCKWAVE Impact Duty™ Sockets are backed by a Lifetime Guarantee and meet ASME industry standards.
