Milwaukee Tool 49-66-6404 Impact Socket 3/4 in 29mm 6-point

Product Description

The MILWAUKEE TOOL 49-66-6404 is a 3/4 inch drive, 29mm impact socket designed for high-torque fastening applications. Built from steel with a black phosphate finish, this 6-point hex socket is rated non-sparking, making it suitable for use in environments where spark risk is a concern. The standard-length design fits most 3/4 inch drive impact wrenches used in industrial, mechanical, and heavy equipment service. Licensed tradespeople and experienced technicians will find this socket suitable for demanding fastener work where impact-rated tooling is required.

This socket is intended for use with 3/4 inch drive pneumatic or electric impact wrenches in commercial, industrial, and heavy-duty service applications. The 29mm hex size is commonly encountered on large fasteners found in heavy equipment, trucks, structural assemblies, and industrial machinery. The non-sparking rating makes it appropriate for use in facilities where flammable vapors or gases may be present. Standard length allows use in open or moderately accessible fastener locations.
