Our SHOCKWAVE™ Impact Duty™ 3/8 in drive six point socket sets feature the boldest, longest lasting markings and extreme impact durability in high-torque applications. The stamped and ink-filled size markings enable you to select the right socket every time throughout the life of the socket. We engineered these six point sockets with high-strength forged steel for optimized performance in heavy-duty applications and a non-slip hex geometry prevents fastener rounding. The dual-hole design and ring groove allow for easy socket attachment and removal. All Milwaukee SHOCKWAVE™ Impact Duty™ sockets are backed by our lifetime guarantee and meet ASME industry standards.
