Milwaukee Tool 49-66-6319 Impact Socket 3/4 in Drive

Product Description

The MILWAUKEE TOOL 49-66-6319 is a 3/4 inch drive, 1-3/4 inch, 6-point impact socket designed for high-torque fastening applications in demanding trade environments. Built from steel with a black phosphate finish, it resists corrosion and wear under repeated impact loads. The non-sparking construction makes it suitable for use in environments where ignition risk is a concern. Standard length geometry keeps it compatible with common impact wrenches and torque equipment. Electricians, industrial mechanics, and heavy equipment technicians will find this socket sized for larger fasteners found on structural hardware, flanges, and machinery assemblies.

This socket is suited for residential, commercial, and industrial applications where a 3/4 inch drive impact wrench is the tool of choice. Typical installation scenarios include mechanical rooms, utility equipment service, structural steel work, and heavy HVAC or plumbing equipment with large hex fasteners. The 1-3/4 inch, 6-point socket size is common on larger bolts and nuts found in industrial piping, equipment mounting frames, and commercial HVAC systems. Its non-sparking designation makes it appropriate for use in refineries, chemical plants, and other facilities with flammable atmosphere requirements.

Key Features

• 3/4 inch drive hex interface for use with standard 3/4 inch impact wrenches and breaker bars
• 1-3/4 inch, 6-point socket size provides full-contact engagement on hex fasteners to reduce rounding
• Non-sparking construction approved for use in flammable or explosive atmospheres
• Black phosphate finish resists corrosion and reduces glare in the field
• Standard length profile fits most impact wrench applications without extensions
• Steel construction rated for repeated high-torque impact use

Compatibility

Designed as an OEM-style replacement and standard-use impact socket for 3/4 inch drive impact wrenches and hand torque tools requiring a 1-3/4 inch, 6-point hex socket.

Installation Notes

This socket is installed and serviced by licensed mechanics, electricians, pipefitters, or other qualified trade professionals. Always confirm the drive size and torque rating of the impact wrench match the socket before use. In non-sparking environments, verify the socket is free of contamination before introducing it to flammable atmospheres. Do not use impact sockets on hand-ratchet tools unless the tool is rated for impact-rated accessories.
