Milwaukee Tool 49-66-6394 Impact Socket 3/4 in 19mm

Product Description

The MILWAUKEE TOOL 49-66-6394 is a 3/4 inch drive, 19mm, 6-point impact socket designed for heavy-duty fastening applications. Built from steel with a black phosphate finish, this standard-length hex drive socket is rated non-sparking, making it suitable for use in environments where ignition risk is a concern. It is intended for use with 3/4 inch drive impact wrenches and is a common choice for industrial maintenance, mechanical, and construction trades where torque output and durability are critical.

This socket fits standard 3/4 inch drive impact wrenches and is applicable across a wide range of commercial and industrial fastening tasks. The 19mm hex size covers common fastener dimensions found in heavy equipment, structural assemblies, and machinery maintenance. Its non-sparking designation makes it appropriate for use in petrochemical, mining, and other potentially flammable or explosive environments where conventional steel sockets present a safety hazard.

Installation Notes

Installation and use should be performed by qualified mechanical or industrial trades professionals familiar with impact tooling.
