Milwaukee Tool 49-66-6301 Impact Socket 3/4 in Drive 5/8 in

Product Description

The MILWAUKEE TOOL 49-66-6301 is a 6-point impact socket designed for heavy-duty fastening applications. Built with a 3/4 inch drive and a 5/8 inch socket size, it is engineered to handle the high-torque output of pneumatic and electric impact wrenches without fracturing or deforming. The steel construction with a black phosphate finish provides corrosion resistance and reduces surface glare on the job. The standard-length design fits typical fastener access points found in mechanical, industrial, and field service environments. Licensed tradespeople and experienced technicians working with impact-rated tools rely on this socket for consistent, reliable performance across demanding fastening tasks.

This socket is suited for use in industrial maintenance, heavy equipment service, automotive, and construction applications where 3/4 inch drive impact tooling is standard. The non-sparking rating makes it appropriate for environments where ignition risk must be controlled, such as fuel system work, confined spaces, or other areas with flammable atmosphere concerns. The standard length profile accommodates most exposed bolt and nut configurations without the need for extensions in typical installations.

Key Features

• 3/4 inch drive accepts standard 3/4 inch impact wrenches and ratchets
• 5/8 inch 6-point socket geometry for maximum contact on hex fasteners
• Non-sparking construction rated for use in ignition-sensitive environments
• Black phosphate finish resists corrosion and reduces light reflection
• Steel construction built to withstand high-torque impact tool output
• Standard length profile fits common fastener access without extensions

Compatibility

Designed as an OEM-style impact socket compatible with standard 3/4 inch drive impact wrenches, ratchets, and torque multipliers used in industrial and heavy-duty trade applications.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with impact tooling safety practices. Always confirm the socket is fully seated on the drive anvil before applying torque, and inspect the socket for cracks or deformation before each use. Do not use impact sockets with hand-ratchet tools not rated for impact loads. In environments with flammable atmospheres, verify all tooling including drives and extensions carries appropriate non-sparking ratings before use.
