The SHOCKWAVE Impact Duty 6-point 1/2-inch drive sockets feature the boldest, most durable markings and demonstrate extreme impact resistance in high-torque applications. Stamped and ink-filled size markings allow you to choose the correct socket every time throughout the life of the socket. We manufactured these standard 6-point sockets with high-strength forged steel to optimize their performance in heavy-duty applications, and designed a non-slip hexagonal geometry to prevent rounding the fastener. The two-hole, one-ring groove design makes it easy to install and remove sockets. All MILWAUKEE SHOCKWAVE Impact Duty sockets are backed by the lifetime warranty and meet ASME industry standards.
