Milwaukee Tool 49-66-6351 Impact Socket 3/4 in Drive

Product Description

The MILWAUKEE TOOL 49-66-6351 is a 6-point impact socket designed for heavy-duty fastening and removal applications. Built on a 3/4 inch drive, it accepts a 1-3/4 inch hex fastener and is manufactured from steel with a black phosphate finish that resists corrosion and reduces glare. Standard length construction keeps the profile compact for use in tight service bays and field installations. This socket is rated non-sparking, making it suitable for environments where ignition risk is a concern. It is installed by licensed electricians, HVAC technicians, plumbers, pipefitters, and general mechanical contractors working with large-diameter fasteners on commercial and industrial equipment.

This socket fits common applications involving large hex-head fasteners found on HVAC equipment, pump flanges, structural connections, and industrial machinery. The 3/4 inch drive sizing is standard for heavy-duty impact wrenches used in commercial service work. The non-sparking and non-insulated construction makes it appropriate for use near flammable materials where spark ignition is a hazard, though it is not rated for live electrical work. Standard length geometry works with most 3/4 inch drive impact wrenches and breaker bars in typical trade toolkits.

Key Features

• 3/4 inch drive with 1-3/4 inch socket size for large hex fasteners
• 6-point contact geometry reduces fastener rounding under high torque
• Non-sparking construction rated for use in ignition-sensitive environments
• Black phosphate finish provides corrosion resistance and low-glare surface
• Standard length profile for compatibility with common 3/4 inch drive impact tools
• Steel construction built for repeated impact driver use without deformation

Compatibility

Designed as an OEM-style impact socket for use with standard 3/4 inch drive impact wrenches and breaker bars in commercial and industrial trade applications.

Installation Notes

Install and remove this socket with the impact wrench or breaker bar powered down and the equipment being serviced de-energized or shut off per applicable lockout/tagout procedures. Verify drive size matches the tool before use. This socket is non-insulated and must not be used on energized electrical connections. Inspect for cracks or deformation before each use and remove from service if damage is found.
