Our SHOCKWAVE Impact Duty™ 1/2" Drive 33MM Deep 6 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 6-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.
