The WILLIAMS COMFORT PRODUCTS JHW31531 is an 11 MM metric universal socket designed for 3/8 inch drive ratchets and extensions. It features an overall length of 1-55/64 inches, making it well-suited for reaching fasteners in tight or confined spaces where a standard socket cannot make proper contact. The universal joint design allows the socket to operate at an angle, giving technicians access to recessed or awkwardly positioned fasteners. At 0.12 pounds, it is a lightweight addition to a professional tool kit.
This socket is intended for trade professionals who regularly work in confined areas — such as HVAC techs accessing equipment fasteners behind panels, plumbers working around pipe runs, or electricians tightening hardware in crowded enclosures. The metric sizing and universal drive make it a practical general-use tool across a wide range of service and installation scenarios where standard sockets fall short.
Designed for use with standard 3/8 inch drive ratchets, breaker bars, and extensions. Compatible with metric fasteners requiring an 11 MM socket.
Installation and service use of this socket should follow standard hand-tool safety practices. Ensure the drive connection is fully seated on the ratchet or extension before applying torque to avoid slippage. When working near energized equipment, follow applicable NFPA 70E electrical safety guidelines and de-energize circuits before accessing fasteners where required. Do not use impact drivers with this socket unless it is rated for impact use.
