Milwaukee Tool 49-66-6255 Impact Socket 1/2 in 23mm 6-pt

Product Description

The MILWAUKEE TOOL 49-66-6255 is a 1/2 inch drive, 23mm impact socket built for high-torque fastening applications in the field or shop. The 6-point hex profile maximizes contact with fastener flats, reducing rounding under load. Constructed from steel with a black phosphate finish, it resists corrosion and withstands the repeated shock loads produced by pneumatic and cordless impact wrenches. At 0.32 pounds and a standard length profile, this socket integrates cleanly into a working tray or roll cabinet without adding bulk. Electricians, plumbers, HVAC technicians, and general contractors rely on this size for structural hardware, pipe flanges, and mechanical connections encountered daily on residential and light commercial jobs.

The 49-66-6255 is suited for any trade application requiring a 23mm fastener driven by a 1/2 inch impact wrench or ratchet. The non-sparking designation makes it appropriate for use in environments where ignition risk must be controlled, including fuel system work and certain electrical service scenarios. Standard length keeps it accessible in tight clearances common in mechanical rooms, equipment pads, and panel installations where a deep socket would foul against adjacent structure.

Key Features

• 1/2 inch drive fits standard impact wrenches, ratchets, and breaker bars
• 6-point hex profile reduces fastener rounding under high-torque impact loads
• Non-sparking construction rated for use in ignition-sensitive environments
• Black phosphate finish provides corrosion resistance and reduces glare
• Standard length profile suits confined installation spaces
• Steel construction handles repeated shock loads from pneumatic and cordless impact tools

Compatibility

Designed for use with 1/2 inch drive impact wrenches, ratchets, and breaker bars accepting standard 1/2 inch square drive accessories. Fits 23mm hex fasteners in residential and light commercial mechanical, plumbing, and electrical applications.

Installation Notes

Install and remove with standard 1/2 inch drive impact tools or hand ratchets. Confirm the socket is fully seated on the fastener before applying torque to avoid rounding. In non-sparking applications, verify that all associated drive tools and extensions also meet the required non-sparking specification for the work environment. Inspect the socket periodically for cracks or deformation and remove from service if damage is found.
