Milwaukee Tool 49-66-6274 Impact Socket 1/2 in 13mm

Product Description

The MILWAUKEE TOOL 49-66-6274 is a 1/2 inch drive, 13mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Built from steel with a black phosphate finish, it delivers corrosion resistance and durability in demanding trade environments. The 6-point geometry maximizes contact with fastener flats, reducing rounding under high-torque impact loads. At a standard length of 3.07 inches and a weight of 0.3 pounds, it fits compactly in a socket set without adding unnecessary bulk. The non-sparking construction makes it suitable for use in environments where ignition hazards are a concern. Electricians, HVAC technicians, plumbers, and general mechanical trades all use this size regularly for equipment installation and service work.

This socket is appropriate for residential and commercial trade applications wherever 13mm fasteners are encountered. Common uses include mounting HVAC equipment, securing electrical panels and enclosures, plumbing fixture installation, and general mechanical assembly. The standard length profile works with most impact-rated extensions and universals for both close-quarters and open-access fastening tasks. Its non-sparking designation makes it a fit for service calls in environments with flammable vapors or gases, such as mechanical rooms, utility spaces, and industrial facilities.

Compatibility

Designed as an OEM-style replacement impact socket compatible with standard 1/2 inch drive impact wrenches, ratchets, and extensions requiring a 13mm 6-point hex socket.

Installation Notes

This socket is installed by hand onto any 1/2 inch drive impact tool or ratchet. Always ensure the socket is fully seated on the drive square and the retaining mechanism is engaged before applying torque. When working near electrical equipment, de-energize circuits per NFPA 70E requirements before beginning fastening or removal tasks. Do not use impact sockets with hand-ratchet-only tools not rated for impact loads, as this can cause socket failure.
