Milwaukee SHOCKWAVE™ Impact Duty 3/8" Drive 21MM Standard 6 Point Socket

MAXIMUM TORQUE REFINEMENT

When your fleet is cycling through thousands of fasteners a week, socket failure isn't just an inconvenience—it is a hit to your bottom line. The Milwaukee 49-66-6144 SHOCKWAVE Impact Duty socket is engineered for the high-vibration environment of modern impact drivers, utilizing premium forged steel that balances hardness for wear resistance with the ductility required to prevent shattering under extreme load. This isn't just a piece of chrome; it’s a high-performance transmission for your tool's torque, ensuring every foot-pound reaches the fastener without loss or rounding.

• / HIGH-STRENGTH FORGED STEEL: Optimized for heavy-duty impact applications, providing the structural integrity needed to survive the world’s most powerful 3/8" impact wrenches.
• / INK-FILLED IDENTIFICATION: Stamped and ink-filled markings ensure that 21mm remains visible after years of grease, oil, and abrasion on the jobsite.
• / NON-SLIP HEX GEOMETRY: The 6-point design contacts the flat surfaces of the bolt rather than the corners, preventing rounding and extending the life of your hardware.
• / DUAL-HOLE PIN HOLE: Designed with a ring groove and dual-hole system to ensure secure attachment to the anvil, preventing accidental socket drops in overhead or tight-clearance work.
