Milwaukee Tool 49-66-6511 Impact Socket 1 in Drive 6-pt

Product Description

The MILWAUKEE TOOL 49-66-6511 is a 1-inch drive, 1-7/16-inch, 6-point hex impact socket designed for heavy-duty fastening applications. Built from steel with a black phosphate finish, this standard-length socket resists corrosion and withstands the high-torque output of pneumatic and hydraulic impact wrenches. The non-sparking construction makes it suitable for use in environments where ignition risk must be controlled. Licensed tradespeople in mechanical, industrial, and construction trades rely on this type of socket for demanding fastener work where standard chrome sockets would crack or slip under impact loads.

This socket is sized for large-fastener applications commonly encountered in heavy equipment service, structural steel work, industrial machinery maintenance, and commercial construction. The 6-point design maximizes contact surface on hex fasteners, reducing rounding and improving torque transfer. The standard length profile fits most impact wrench drive setups without requiring an extension. It is packaged as a single unit, making it a practical replacement or addition to an existing drive set.

Key Features

• 1-inch drive size for use with heavy-duty impact wrenches
• 1-7/16-inch socket size for large hex fasteners
• 6-point geometry maximizes contact and reduces fastener rounding
• Non-sparking construction suitable for controlled-environment applications
• Black phosphate finish resists corrosion and reduces glare
• Standard length profile for direct drive use without extension

Compatibility

Designed as an OEM-style impact socket compatible with 1-inch drive impact wrenches and ratchets accepting standard square-drive accessories.

Installation Notes

This socket is installed and used by licensed mechanics, millwrights, ironworkers, and industrial maintenance technicians. Always ensure the impact wrench is depressurized or powered down before changing sockets. Confirm the socket is fully seated on the drive anvil and the retaining pin or detent is engaged before applying torque. Do not use impact sockets with standard hand-drive ratchets, as the wall thickness and metallurgy are optimized for impact use only.
