Milwaukee Tool 49-66-6422 Impact Socket 3/4 in 47mm

Product Description

The MILWAUKEE TOOL 49-66-6422 is a 3/4 inch drive, 47mm, 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 hydraulic impact wrenches. The non-sparking construction makes it suitable for use in environments where ignition risk is a concern. Licensed trade professionals and industrial mechanics rely on this socket for demanding bolting and unbolting tasks where a standard chrome socket would fail under repeated impact stress.

This socket is suited for industrial, commercial, and heavy equipment maintenance applications where a 3/4 inch drive impact wrench is the tool of choice. The 47mm hex socket size is commonly used on large fasteners found in heavy machinery, structural assemblies, and commercial vehicle service. The standard length profile allows access in typical underhood and equipment bay configurations without requiring an extension in most setups.

Key Features

• 3/4 inch drive fits standard 3/4 inch impact wrenches and breaker bars
• 47mm 6-point hex socket provides full-contact engagement on fastener flats, reducing rounding
• Non-sparking construction rated for use in hazardous or flammable environments
• Black phosphate finish resists corrosion and reduces light glare during service
• Steel construction handles repeated high-torque impact cycles without deforming
• Standard length profile for general-purpose access

Compatibility

Designed as an OEM-style impact socket compatible with standard 3/4 inch drive impact wrenches, torque wrenches, and breaker bars used in heavy equipment, industrial, and commercial vehicle service applications.

Installation Notes

Installation and removal should be performed by a qualified mechanic or trades professional familiar with impact tooling. Always verify the drive size and socket size match the fastener and tool before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Never use impact sockets with hand-ratchet tools in applications exceeding the tool manufacturer rated torque.
