The WILLIAMS COMFORT PRODUCTS JHWHD-644 is a deep SAE socket designed for high-torque fastener work in professional trade applications. Built with a 1/2 inch drive and a 1.375 inch opening, it provides a 3.5 inch overall length to reach recessed fasteners in tight assemblies. The lobular internal geometry engages 6-point fasteners fully, reducing the risk of rounding under load. Electricians, plumbers, HVAC technicians, and general trade professionals use this socket when standard-depth sockets cannot reach the fastener head due to depth or obstruction.
This deep socket is suited for residential and commercial service work where fasteners are countersunk, stud-mounted, or otherwise recessed beyond the reach of a standard socket. Typical applications include equipment panel assembly, pipe flange bolting, and mechanical room fastener work. The SAE sizing makes it the appropriate choice for inch-standard fasteners commonly found on domestic HVAC equipment, plumbing fixtures, and electrical enclosures. It is sold individually and fits standard 1/2 inch drive ratchets and breaker bars.
Designed as an OEM-style deep socket for use with standard 1/2 inch drive ratchets and drive tools requiring a 1.375 inch SAE opening.
This socket is installed and used by licensed trade professionals including HVAC technicians, plumbers, and electricians during equipment service and installation. Always ensure the drive tool and socket are fully engaged before applying torque to avoid slippage. Inspect the socket for cracks or wear before each use, and do not use adapters that reduce the drive size when applying high torque loads.
