Milwaukee Tool 49-66-6386 Impact Socket 3/4 in 48mm

Product Description

The MILWAUKEE TOOL 49-66-6386 is a 3/4 inch drive, 48mm, 6-point hex impact socket built for heavy-duty fastening applications. Constructed from steel with a black phosphate finish, it is engineered to handle the high-torque output of impact wrenches without cracking or rounding fasteners. The non-sparking design makes it suitable for use in environments where ignition hazards are a concern. Standard length geometry keeps the socket compact for work in tighter spaces. Licensed HVAC technicians, industrial mechanics, and pipefitters commonly reach for sockets in this size range when working on large mechanical assemblies and heavy equipment.

This socket is sized for large-format fasteners commonly encountered in commercial HVAC equipment, heavy mechanical systems, and industrial piping installations. The 48mm hex size and 3/4 inch drive make it compatible with 3/4 inch drive impact wrenches used in professional trade settings. The non-sparking characteristic is particularly relevant for use near flammable gases or in classified hazardous locations where a spark could present a safety risk.

Key Features

• 3/4 inch drive fits standard 3/4 inch drive impact wrenches and ratchets
• 48mm 6-point hex socket provides full-contact engagement to reduce fastener rounding
• Non-sparking design suitable for use in hazardous or flammable environments
• Steel construction with black phosphate finish for corrosion resistance and durability
• Standard length profile for use in space-constrained installations
• Not insulated — not rated for live electrical work

Compatibility

Designed as an OEM-style replacement and service socket for use with 3/4 inch drive impact wrenches and torque tools requiring a 48mm 6-point hex socket.

Installation Notes

Installation and removal of large fasteners with impact sockets should be performed by qualified trade professionals using properly rated impact-drive equipment. Always confirm the drive tool torque rating is appropriate for the fastener and application before use. Power down or de-energize any equipment being serviced before applying torque to fasteners. Do not use impact sockets with standard hand-ratchet tools beyond their rated capacity.
