Milwaukee Tool 49-66-6424 Impact Socket 3/4 in 49mm

Product Description

The MILWAUKEE TOOL 49-66-6424 is a 3/4 inch drive, 49mm impact socket designed for heavy-duty fastening and removal applications. Built with a 6-point hex drive profile, it delivers full contact on fastener flats, reducing the risk of rounding under high torque. The socket is constructed from steel with a black phosphate finish that resists corrosion and reduces glare in the field. Standard length geometry makes it a straightforward fit in most impact wrench setups. It carries a non-sparking rating, making it appropriate for use in environments where ignition risk is a concern. Licensed trades and industrial mechanics working with large fasteners will find this socket a direct fit for impact gun applications.

This socket is suited for commercial and industrial mechanical work, heavy equipment service, and structural fastener applications where a 3/4 inch drive impact wrench is in use. The 49mm size addresses large-format hex fasteners common in machinery, HVAC equipment mounting, heavy plumbing infrastructure, and structural steel assembly. The non-sparking characteristic makes it appropriate for petrochemical, utility, and other controlled-environment job sites where standard steel tooling is prohibited. Standard length suits general access points without the need for extensions in most installations.

Key Features

Compatibility

Designed for use with 3/4 inch drive impact wrenches and ratchets. Compatible with standard 3/4 inch drive tooling configurations. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation and fastener work with this socket should be performed by qualified mechanics or trade professionals familiar with impact tooling and torque requirements. Ensure the impact wrench is powered down or air supply is disconnected before seating or removing the socket. Do not use impact sockets with hand ratchets as the metallurgy differs between impact and chrome-finish hand tool sockets. On job sites with ignition hazards, verify the non-sparking rating meets the specific site safety standard before use.
