Milwaukee SHOCKWAVE™ Impact Duty 3/4″ Drive 1-7/8″ Standard 6 Point Socket

MAXIMUM TORQUE TRANSFER DURABILITY

For fleet managers and heavy equipment mechanics, the Milwaukee 49-66-6321 represents more than just a 1-7/8″ socket; it is a critical investment in jobsite uptime and mechanical precision. When operating high-torque 3/4″ drive impact wrenches, the mechanical stress on a socket can lead to catastrophic failure or fastener rounding. This SHOCKWAVE Impact Duty solution utilizes heat-treated forged steel to ensure that every foot-pound of torque is delivered directly to the fastener, minimizing energy loss and maximizing your fleet’s efficiency in the field.

• / High-Strength Forged Steel: Engineered to handle the extreme rotational stress of heavy-duty impacts without fracturing or deforming.
• / Non-Slip Hex Geometry: The 6-point design grips the flats of the fastener rather than the corners, significantly reducing the risk of rounding and extending the life of high-value hardware.
• / Bold Ink-Filled Markings: Stamped and filled size labels ensure rapid identification in low-light environments, even after years of abrasive industrial use.
• / Dual-Hole Attachment: Features a cross-pin hole and ring groove design to ensure the socket stays securely locked onto the anvil during high-vibration applications.
