Milwaukee Tool 49-66-6369 Impact Socket 3/4 in 31mm

Product Description

The MILWAUKEE TOOL 49-66-6369 is a 3/4 inch drive, 31mm, 6-point hex impact socket designed for heavy-duty fastening applications. Built from steel with a black phosphate finish, this standard-length socket resists corrosion and withstands the high-torque output of pneumatic and electric impact wrenches. The 6-point contact geometry reduces rounding on fastener heads under load. It is non-sparking, making it appropriate for use in environments where ignition risk is a concern. Licensed trades and industrial mechanics reach for this socket when working on large-diameter fasteners in demanding service conditions.

This socket is suited for commercial and industrial applications where a 3/4 inch drive tool is required, including heavy equipment service, structural mechanical work, and large-format HVAC or mechanical system installations. The standard-length profile fits tight spaces better than deep sockets while still providing full engagement on 31mm hex fasteners. It is a direct-fit accessory for 3/4 inch drive impact wrenches and ratchets.

Key Features

• 3/4 inch drive size for high-torque impact tool compatibility
• 31mm socket size with 6-point hex geometry for secure fastener engagement
• Non-sparking construction rated for use in ignition-sensitive environments
• Steel construction with black phosphate finish for corrosion resistance
• Standard-length profile for general-purpose fastening tasks
• Not insulated — not rated for live electrical work

Compatibility

Designed as an OEM-style accessory for 3/4 inch drive impact wrenches and ratchets that accept standard hex impact sockets.

Installation Notes

Installation is performed by mechanics and trade professionals using 3/4 inch drive impact wrenches or ratchets. Confirm the fastener size matches the 31mm socket opening before applying torque. Inspect the socket for cracks or deformation before each use, and never use impact sockets on non-impact hand-drive tools where drive geometry may differ. This socket is not insulated and must not be used on or near energized electrical equipment.
