Milwaukee Tool 49-66-6398 Impact Socket 3/4 in 23mm

Product Description

The MILWAUKEE TOOL 49-66-6398 is a 3/4 inch drive, 23mm impact socket designed for heavy-duty fastening applications in trade and industrial environments. Built from steel with a black phosphate finish, this 6-point socket delivers reliable torque transfer while resisting corrosion. 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 3/4 inch drive impact wrenches and torque tools used by mechanics, pipefitters, and industrial maintenance technicians.

This socket is suited for use in environments where non-sparking tool requirements apply, including petrochemical, industrial, and other hazardous work areas. The 6-point drive profile engages fastener flats fully, reducing the chance of rounding under high-torque impact loads. At 1.41 pounds and a standard length profile, it fits naturally into a working socket set alongside other 3/4 inch drive tooling.

Key Features

• 3/4 inch drive size compatible with standard impact wrenches and torque multipliers
• 23mm socket size with 6-point hex drive profile for full-flat fastener engagement
• Non-sparking construction rated for use in ignition-sensitive environments
• Steel construction with black phosphate finish for corrosion resistance
• Standard length design for general-access fastening applications
• Not insulated — confirm appropriate PPE and lockout procedures before use

Compatibility

Designed as an OEM-style impact socket for use with standard 3/4 inch drive impact wrenches, ratchets, and torque tools accepting 23mm fasteners.

Installation Notes

This socket is installed and used by mechanics, millwrights, pipefitters, and industrial maintenance technicians working with 3/4 inch drive impact equipment. Always ensure the drive tool is powered down or air supply is disconnected before changing sockets. This socket is not insulated — do not use on energized fasteners. Confirm non-sparking tool requirements with your site safety plan before deployment in classified hazardous locations.
