The WILLIAMS COMFORT PRODUCTS JHW31817 is a metric deep socket designed for professional fastener removal and installation in demanding trade environments. Built for 3/8 inch drive tools, this socket fits 17 MM fasteners and features a 2.5 inch overall length that provides clearance for recessed or extended bolt heads. The lobular internal opening design reduces contact stress on fastener corners, helping prevent rounding during high-torque applications. Sold individually, this socket suits HVAC, plumbing, and mechanical service work where metric fasteners are common.
This deep socket is intended for use with 3/8 inch drive ratchets, extensions, and torque wrenches. The deep profile makes it suitable for reaching nuts on long studs or bolts that sit below a surface. It engages both 6-point and 12-point fasteners, giving technicians flexibility across a wide range of hardware. Residential and light commercial service calls often require metric sockets of this size for equipment mounting hardware and panel fasteners.
Designed as a standard 3/8 inch drive metric deep socket for use with 17 MM fasteners across a range of trade and mechanical service applications.
This socket is installed by trade professionals including HVAC technicians, plumbers, and electricians during equipment service and installation. Ensure the drive connection is fully seated on the ratchet or extension before applying torque. Inspect the socket for cracks or wear before each use, and do not use adapters that exceed the drive rating of the tool. Always confirm fastener size before applying force to avoid damaging hardware.
