Milwaukee Tool 49-66-6612 Impact Socket 1 in 58mm 6-pt

Product Description

The MILWAUKEE TOOL 49-66-6612 is a 1-inch drive, 58mm, 6-point hex impact socket designed for heavy-duty fastening applications in trade and industrial environments. Built from steel with a black phosphate finish, this standard-length socket resists corrosion and reduces glare in the field. The 6-point geometry maximizes contact with fastener faces, reducing the risk of rounding under high-torque impact loads. Rated as non-sparking, it is suited for use in environments where ignition risk must be controlled. Mechanical contractors, industrial maintenance techs, and heavy equipment service professionals are the primary installers of this socket.

This socket is intended for use with 1-inch drive impact wrenches in applications requiring a 58mm hex drive. Typical use cases include heavy equipment assembly and disassembly, structural fastening, and large-diameter nut removal in industrial, construction, and fleet maintenance settings. The standard-length design fits most 1-inch drive impact tools without requiring an extension in the majority of installations.

• Not insulated — not rated for live electrical work

Compatibility

Designed as an OEM-style impact socket for use with 1-inch drive impact wrenches requiring a 58mm 6-point hex socket.

Installation Notes

This socket is installed and used by mechanical contractors, industrial maintenance technicians, and fleet service professionals. Ensure the impact wrench is fully depressurized or de-energized before changing sockets. Always confirm the socket is fully seated on the drive anvil and the retaining pin or ring is secured before applying torque. Do not use this socket with hand-drive ratchets, as impact sockets are engineered specifically for the shock loads produced by impact tools.
