Milwaukee Tool 49-66-6515 Impact Socket 1 in Drive

Product Description

The MILWAUKEE TOOL 49-66-6515 is a 6-point impact socket designed for use with 1 inch drive impact wrenches and ratchets. Built from steel with a black phosphate finish, this socket accepts a 1-11/16 inch hex fastener and delivers the torque resistance required for heavy-duty industrial and mechanical applications. The non-sparking construction makes it suitable for environments where spark hazard is a concern. Standard length design fits most impact drive setups without requiring an extension in typical fastening scenarios. At 4.8 pounds, the socket is sized for demanding applications where durability under repeated impact loading is essential.

This impact socket is suited for industrial maintenance, heavy equipment service, and structural assembly work where 1 inch drive tooling is standard. The 6-point contact geometry reduces fastener rounding under high-torque impact conditions, making it appropriate for professionals working with large-diameter hex fasteners in both shop and field environments. Electricians, millwrights, ironworkers, and heavy equipment technicians are the primary installers.

Key Features

• 1 inch drive fits standard heavy-duty impact wrenches and ratchets
• 1-11/16 inch 6-point socket provides full-face contact on hex fasteners, reducing rounding
• Non-sparking construction rated for use in spark-sensitive environments
• Steel body with black phosphate finish resists corrosion and reduces glare
• Standard length profile for direct drive use without an extension in most applications

Compatibility

Designed as an OEM-style replacement or supplemental socket for 1 inch drive impact wrenches and ratchets accepting standard square-drive sockets in heavy-duty trade and industrial applications.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with impact drive tooling and torque requirements for the target fastener. Confirm the socket is fully seated on the drive anvil and the retaining ring or pin is engaged before applying torque. Never use impact sockets on hand-ratchet drives rated for hand-torque only, as impact loading can fracture standard chrome sockets. Inspect the socket for cracks or deformation before each use and remove from service if any damage is present.
