The MILWAUKEE 242pc. 1/4”, 3/8”, & 1/2” Drive Metric & SAE Ratchet & Socket Set features 6-point sockets with FOUR FLAT Sides that deter rolling and are wrench compatible. These sockets have optimized geometry to reduce bolt rounding and stripping. The 90-tooth ratchets provide 4° of arc swing and a slim profile for work in tighter spaces. The set also includes SHOCKWAVE Impact Duty sockets with the boldest, longest-lasting markings and extreme impact durability in high torque applications. The stamped and ink-filled size marking enables you to select the right socket every time throughout the life of the socket.

The trays are designed for use in PACKOUT Drawers Tool Boxes (48-22-8444, 48-22-8443, 48-22-8442, 48-22-8447).
