Drive 10MM Deep 6 Point Socket features the boldest, longest-lasting markings and extreme impact durability in high torque applications. The stamped and ink-filled size marking enables users to select the right socket every time throughout the life of the socket. Milwaukee engineered this 6-point standard socket 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 SHOCKWAVE Impact-Duty Sockets are backed by a Lifetime Guarantee and meet ASME industry standards.
