Milwaukee Tool 49-66-7841 Impact Socket 1 in Drive

Product Description

The MILWAUKEE TOOL 49-66-7841 is a deep 4-point impact socket designed for use with 1 inch square drive impact wrenches and compatible adapters. Built from steel with a black phosphate finish, this socket measures 2.126 inches overall length and is engineered for high-torque applications where durability and marking legibility matter. The non-sparking construction makes it suitable for environments where spark hazard is a concern. Stamped and ink-filled diameter markings resist wear over time, keeping size identification reliable through extended use in the field.

This socket is intended for trade professionals working in mechanical, industrial, and heavy-equipment service settings where a 1 inch drive impact wrench is standard. The deep length and 4-point drive geometry are suited for fasteners requiring a secure, high-torque grip. The dual hole design and groove aid attachment and retention when working with extensions or in overhead and confined installations.

Key Features

• 1 inch square drive, 13/16 inch socket size in a deep-length configuration
• 4-point drive geometry for high-torque fastener engagement
• Non-sparking construction suitable for hazardous or spark-sensitive environments
• Stamped and ink-filled diameter markings for long-term wear resistance and easy identification
• Dual hole design and groove for easier attachment and retention with extensions
• Black phosphate finish for corrosion resistance

Compatibility

Optimized for use with 1 inch drive impact wrenches and adapters. Designed as a replacement or addition to standard 1 inch drive impact socket sets used in mechanical and industrial service applications.

Installation Notes

Installation and use should be performed by qualified mechanics or trade professionals familiar with high-torque impact tooling. Before use, verify that the socket is fully seated on the drive and that the retaining pin or groove is properly engaged. Do not use impact sockets with hand ratchets or torque wrenches, as impact-rated sockets are designed specifically for power impact tools. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
