Our SHOCKWAVE Impact Duty™ 1/2 in drive six-point sockets 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 standard 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 assurance and meet ASME industry standards.
