Williams Comfort Products JHW1214SC Combination Wrench 7/16 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1214SC is a 7/16-inch combination wrench designed for professional trade use in mechanical, HVAC, plumbing, and electrical applications. It features a SUPERCOMBO open end and a SUPERTORQUE box end on a single tool, both sized identically at 7/16 inch. The open end uses specially designed grooves to redirect wrench force away from fastener corners, reducing rounding risk. The box end applies wrenching force to the flat surfaces of hex fasteners rather than the corners, allowing higher torque without deforming the fastener. Overall length is 7.1 inches and the tool weighs 0.111 pounds.

This wrench is suited for residential and commercial service work where fastener access and torque precision matter. It performs on all common 6-point hex fasteners and meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for high-precision torque applications. HVAC technicians, plumbers, and electricians will find it useful for equipment panels, service valves, and mechanical connections that require a reliable combination wrench in a compact form factor.
