Milwaukee Tool 49-66-6520 Impact Socket 1 in Drive 2 in

Product Description

The MILWAUKEE TOOL 49-66-6520 is a 1-inch drive, 2-inch impact socket designed for high-torque fastening applications in industrial and heavy trade work. Built from steel with a black phosphate finish, this 6-point hex drive socket delivers reliable grip on hex fasteners under power-tool load. The non-sparking construction makes it suited for environments where spark hazard is a concern. At 6.04 pounds and standard length, it is a direct fit for 1-inch drive impact wrenches used by electricians, pipefitters, ironworkers, and maintenance trades on demanding job sites.

This socket is used in industrial maintenance, structural steel, pipeline, and heavy equipment service applications where a 1-inch drive impact wrench is the tool of choice. The 6-point contact geometry reduces the risk of fastener rounding under high torque, making it appropriate for both installation and removal of stubborn or high-load hex fasteners. Standard length suits most general-purpose impact applications without the clearance concerns of deep or extended sockets.

Key Features

• 1-inch drive size for use with heavy-duty impact wrenches
• 2-inch socket size in 6-point hex drive configuration
• Non-sparking construction rated for hazardous or spark-sensitive environments
• Black phosphate finish resists corrosion and reduces glare
• Steel construction for durability under sustained impact torque loads
• Standard length profile for general-purpose accessibility

Compatibility

Designed as an OEM-style replacement socket compatible with standard 1-inch square drive impact wrenches used in industrial and heavy trade applications.

Installation Notes

Installation is performed by qualified tradespeople using a 1-inch drive impact wrench. Verify the socket is fully seated on the drive anvil and the retaining pin or ring is engaged before applying torque. Always confirm the fastener size matches the 2-inch socket before use to avoid socket or fastener damage. Follow applicable workplace safety codes and PPE requirements when operating in spark-sensitive environments.
