Milwaukee Tool 49-66-6395 Impact Socket 3/4 Drive 20mm

Product Description

The MILWAUKEE TOOL 49-66-6395 is a 3/4 inch drive, 20mm impact socket designed for heavy-duty fastening and removal applications. Built from steel with a black phosphate finish, it features a 6-point hex drive geometry that maximizes contact with fastener flats, reducing rounding under high torque. Standard length construction keeps it compatible with a wide range of impact wrenches and drive extensions. This socket is rated non-sparking, making it suitable for use in environments where ignition risk is a concern. Installation and removal of heavy equipment fasteners across mechanical, industrial, and trade service work are its primary use cases.

This socket is well suited for licensed mechanics, HVAC technicians, plumbers, and electricians working with large-diameter fasteners in tight service environments. The 3/4 inch drive size targets mid- to heavy-duty applications where a 1/2 inch drive lacks the torque capacity needed. Standard length fitment allows use with most 3/4 inch drive impact wrenches without requiring an extension in typical access situations. Non-sparking construction makes it appropriate for controlled or hazardous service environments where spark suppression is required.

Key Features

• 3/4 inch drive with 20mm 6-point hex socket for maximum fastener contact and reduced rounding
• Non-sparking construction rated for use in environments with ignition risk
• Black phosphate finish provides corrosion resistance and reduces glare in the field
• Standard length profile fits most 3/4 inch drive impact wrenches and extensions
• Steel construction built to withstand repeated high-torque impact use

Compatibility

Designed as an OEM-style impact socket compatible with standard 3/4 inch drive impact wrenches and ratchets.

Installation Notes

This socket is installed by trade professionals using 3/4 inch drive impact wrenches or ratchets. Always ensure the socket is fully seated on the drive anvil before applying torque. Inspect the socket for cracks or deformation before each use, and do not use hand-socket adapters with impact-rated tools. Follow applicable workplace safety codes when operating in classified or hazardous environments where non-sparking tools are required.
