Milwaukee Tool 49-66-6257 Impact Socket 1/2 in 25mm

Product Description

The MILWAUKEE TOOL 49-66-6257 is a 25mm, 6-point impact socket built for use with 1/2 inch drive impact wrenches and rattle guns in professional trade applications. Constructed from steel with a black phosphate finish, it is rated non-sparking, making it suitable for use in environments where spark ignition is a concern. The standard-length design fits most impact driver setups without clearance issues. At 0.34 pounds, it is compact enough for confined fastening tasks while maintaining the wall thickness required to handle high-torque impact loads without cracking or rounding off fastener heads.

This socket is intended for use by HVAC technicians, electricians, plumbers, pipefitters, and general mechanical contractors who rely on 1/2 inch drive impact tools. The 25mm hex drive size is common in equipment fasteners, flanged connections, and structural hardware encountered across residential and commercial job sites. The 6-point design engages fastener flats rather than corners, reducing the risk of rounding under high torque. The non-sparking designation makes it appropriate for use near gas lines, fuel systems, or other ignition-sensitive environments.

Key Features

• 1/2 inch drive fits standard impact wrenches and torque multipliers
• 25mm 6-point socket engages fastener flats to reduce rounding under high torque
• Steel construction with black phosphate finish for corrosion resistance
• Non-sparking design for use in ignition-sensitive environments
• Standard length fits most impact driver setups without clearance limitations
• Lightweight at 0.34 pounds for reduced fatigue during extended use

Compatibility

Designed as an OEM-style impact socket for use with standard 1/2 inch drive impact wrenches and hand ratchets in trade and industrial applications.

Installation Notes

This socket is installed and used by licensed tradespeople including HVAC technicians, electricians, and plumbers. Always ensure the impact wrench is powered off and the air supply is disconnected before changing sockets. Verify the socket is fully seated on the drive anvil and the retaining pin or ring is engaged before applying torque. Do not use impact sockets with standard hand-tool ratchets beyond their rated capacity.
