Milwaukee SHOCKWAVE Impact Duty 3/4" Drive 21MM Standard 6 Point Socket 49-66-6359
ELITE IMPACT TORQUE TRANSFERENCE
When your fleet is operating 3/4-inch high-torque impact wrenches, the accessory becomes the critical failure point unless it is engineered for the strain. This Milwaukee SHOCKWAVE Impact Duty™ 21MM standard socket is purpose-built to bridge the gap between heavy-duty power and stubborn fasteners, ensuring every foot-pound of torque is delivered with precision. Forged from high-strength steel, this socket is designed to withstand the high-cycle fatigue inherent in industrial and heavy mechanical environments.
- / STAMPED & INK-FILLED MARKINGS: Ensure rapid identification in low-light or greasy conditions with size labels that won't rub off over time.
- / HIGH-STRENGTH FORGED STEEL: Engineered for the highest torque applications, providing the structural integrity needed for fleet-wide reliability.
- / NON-SLIP HEX GEOMETRY: Protects your investment by driving the flats of the fastener, preventing rounding and reducing costly downtime.
