Milwaukee Tool 49-66-7843 Impact Socket 1 in Drive

Product Description

The MILWAUKEE TOOL 49-66-7843 is a deep 6-point impact socket designed for use with 1 inch drive impact wrenches and compatible adapters. Built from steel with a black phosphate finish, this socket measures 1-1/8 inches across the drive face and 2.126 inches in overall length. It carries a non-sparking designation, making it appropriate for use in environments where ignition risk is a concern. The stamped and ink-filled size markings resist wear, keeping the socket identifiable through heavy use. This socket is backed by a lifetime guarantee covering impact sockets and extensions, and it meets ASME industry standards for impact-rated tooling.

This socket is suited for heavy-duty industrial, mechanical, and maintenance applications where a 1 inch drive impact wrench is the standard tool. The deep length accommodates fasteners that extend above the mating surface, which is common in heavy equipment, truck chassis, and structural assembly work. The dual hole design and groove simplify attachment and retention on the drive anvil, reducing fumbling during high-volume fastening tasks. Licensed tradespeople including millwrights, diesel mechanics, ironworkers, and heavy equipment technicians are the primary users of this socket size and drive configuration.

Installation Notes

This socket is installed and removed by mechanical technicians, millwrights, and tradespeople using 1 inch drive impact wrenches. Always verify the fastener drive size matches the socket before applying torque. Inspect the socket for cracks, deformation, or worn markings before each use and remove from service if damage is found. Do not use impact sockets with hand ratchets or torque wrenches, as impact-rated and hand-tool drive systems are not interchangeable.
