Milwaukee Tool 49-66-6721 Universal Joint Socket Adapter

Product Description

The MILWAUKEE TOOL 49-66-6721 is a universal joint socket adapter with a 1/4 inch female drive. It allows a socket drive to pivot at an angle, enabling fastener access in tight or obstructed spaces where a straight drive cannot reach. The adapter measures 1.45 inches in length and 0.62 inches in both height and width, making it compact enough for confined work areas. Weighing 0.1 pounds, it is a lightweight addition to any socket set. Licensed electricians, plumbers, HVAC technicians, and mechanical tradespeople use this type of adapter when working around obstacles in equipment enclosures, panels, or mechanical assemblies.

This universal joint adapter is suited for use in residential and commercial service applications where angled fastener access is needed. Typical scenarios include equipment installation or repair involving recessed fasteners, hard-to-reach bolts near walls or structural members, or tight equipment cabinets. It is designed for hand-tool use with 1/4 inch drive sockets and ratchets.
