Milwaukee Tool 49-66-6322 Impact Socket 3/4 in Drive

Product Description

The MILWAUKEE TOOL 49-66-6322 is a 3/4 inch drive, 1-15/16 inch, 6-point impact socket designed for high-torque fastening applications in industrial and trade environments. Constructed from steel with a black phosphate finish, this standard-length socket resists corrosion and withstands the repeated shock loads generated by impact wrenches. The non-sparking designation makes it suitable for use in environments where ignition hazards are a concern. Electricians, pipefitters, millwrights, and heavy equipment technicians will find this socket sized for large fasteners common in structural, mechanical, and utility work.

This socket is sized for 1-15/16 inch hex fasteners and accepts a 3/4 inch drive impact wrench or ratchet. The standard length profile fits most open-access bolting situations without extension. Its non-sparking, non-insulated construction makes it appropriate for use near flammable vapors or gases where spark-free tooling is required by site safety protocols. It is well suited for commercial, industrial, and heavy-duty trade applications including HVAC equipment installation, large pump and motor service, and structural steel work.

Key Features

• 3/4 inch drive fits standard heavy-duty impact wrenches and ratchets
• 1-15/16 inch, 6-point socket geometry maximizes contact with fastener flats and reduces rounding
• Non-sparking construction approved for use in ignition-sensitive environments
• Black phosphate finish provides corrosion resistance and reduces glare
• Standard length profile for direct-access fastening without extensions
• Steel construction rated for the shock loads produced by impact drivers

Compatibility

Designed as an OEM-style replacement and standard-fit impact socket for 3/4 inch drive impact wrenches and ratchets accepting 1-15/16 inch hex fasteners.

Installation Notes

Installation and removal of large fasteners with impact tooling should be performed by qualified tradespeople following applicable site and safety codes. Always verify the socket is fully seated on the drive anvil and fastener before applying torque. De-energize or lock out equipment before servicing fasteners on electrical or mechanical systems. Do not use impact sockets with hand-ratchet tools, as the metallurgy and wall thickness differ from hand-socket designs.
