Milwaukee SHOCKWAVE™ Impact Duty 1/2″ Drive 21MM Standard 6 Point Socket

SUPREME FASTENER PROTECTION & VISIBILITY

When you are managing a fleet of high-torque impact wrenches, the weakest link is often the interface between the anvil and the fastener. The Milwaukee 49-66-6253 SHOCKWAVE Impact Duty socket is engineered to bridge that gap, providing industrial-grade durability that ensures your tools perform at their peak without stripping out hardware or wasting time on size identification. Built for the rigors of heavy-duty shop environments, this socket maximizes your long-term fleet ROI by outlasting standard chrome or inferior impact alternatives.

• / FORGED STRENGTH: High-strength forged steel construction handles the extreme torque of 1/2″ impact drivers without fracturing under load.
• / NON-SLIP GEOMETRY: The 6-point hex design applies pressure to the flats of the fastener rather than the corners, significantly reducing rounding and downtime.
• / PERMANENT IDENTIFICATION: Stamped and ink-filled size markings ensure your crew grabs the 21mm every time, even after years of heavy jobsite abrasion.
• / DUAL-HOLE SECURE ATTACHMENT: Integrated dual-hole design and ring groove allow for a reliable connection to either friction ring or pin-detent anvils.
