The SHOCKWAVE Impact Duty 3/8″ Drive 6 Point 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 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 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.
