The MILWAUKEE SHOCKWAVE Impact Duty 1 Drive 7PC MM & 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. All MILWAUKEE SHOCKWAVE Impact Duty Sockets are backed by their Lifetime Guarantee and meet ASME industry standards.
