The Milwaukee SHOCKWAVE Impact Duty 1 in. Drive 7PC MM and SAE Wheel Service Socket PACKOUT Set features the boldest, longest-lasting markings. The stamped and ink-filled size markings enable you to select the right socket every time throughout the life of the socket. The 4 and 6-point metric and SAE sockets are engineered with high-strength forged steel for optimized performance in high stress applications, and a non-slip hex geometry prevents fastener rounding. The dual-hole design and ring groove allow for easy socket attachment and removal. The set is organized in a PACKOUT Compact Organizer with a clear top to identify parts at a glance easily. The Compact Organizer is part of the Milwaukee PACKOUT Modular Storage System, allowing for storage customization and easy transport of tools and accessories.
