Milwaukee Tool 49-66-7844 1 in Drive 1-1/4 in Impact Socket

Product Description

The MILWAUKEE TOOL 49-66-7844 is a heavy-duty deep impact socket designed for use with 1 inch drive impact wrenches and compatible adapters. Built from steel with a black phosphate finish, this socket features a 6-point hex drive configuration and measures 2.126 inches in overall length. It is classified as a deep socket, making it suited for fasteners that require additional reach. The non-sparking design adds a layer of safety in environments where ignition risk is a concern. Stamped and ink-filled diameter markings resist wear over repeated use in demanding shop and field conditions. Mechanical and industrial technicians working with heavy equipment, trucks, and large fasteners are the primary installers.

This socket is built for applications requiring a 1 inch drive torque tool and a 1-1/4 inch fastener size. The deep length style accommodates extended bolts and recessed hardware commonly found in heavy-duty automotive, fleet maintenance, construction equipment, and industrial machinery service work. The dual hole design and groove support pin and retaining ring attachment methods standard to 1 inch drive systems.
