The WILLIAMS COMFORT PRODUCTS JHW1212RS is a combination wrench with a 3/8-inch opening, rounded profile, and an overall length of 7 1/32 inches. It combines an open-end jaw with a ratcheting box-end head in a single precision-forged tool. The open end features the SUPERCOMBO design, which redirects wrenching force away from fastener corners to reduce rounding. The box end uses the SUPERTORQUE design, applying force to the flat surfaces behind the fastener points rather than at the corners, allowing higher torque without deforming hex fasteners. Manufactured from special alloy steel that is precision forged and heat treated, this wrench is built for repeated use in demanding trade environments.
This wrench is suited for mechanical, plumbing, and HVAC service work where fastener access is limited. The ratcheting box end features up to 80 teeth, which shortens the swing arc needed to turn a fastener in confined spaces. The longer handle is sized for increased leverage and balanced grip. It is sold individually and is appropriate for any trade professional who works regularly with 3/8-inch hex fasteners in tight or obstructed locations.
Designed for use with 3/8-inch hex fasteners across general mechanical, HVAC, plumbing, and electrical trade applications.
This wrench is a hand tool used by licensed tradespeople across HVAC, plumbing, electrical, and mechanical service work. Before applying torque to fasteners on pressurized or energized systems, follow all applicable lockout/tagout procedures and relevant codes including NEC or IFGC where applicable. Inspect the wrench for cracks or wear before each use and do not use extensions or cheater bars on the ratcheting box end.
