Williams Comfort Products QJOM7A Torque Wrench Head 7MM

Product Description

The WILLIAMS COMFORT PRODUCTS QJOM7A is a 7 MM open-end torque wrench head designed for precision fastening in metric applications. It accepts a J-type shank measuring 0.425 inches and delivers a maximum torque output of 6 ft-lb. This interchangeable head mounts to a compatible torque wrench handle, allowing technicians to swap head sizes without replacing the entire tool. It is built for trade professionals who require accurate, repeatable torque application on metric fasteners in HVAC, plumbing, and mechanical service work.

This torque wrench head is suited for residential and light commercial service applications where compact tool access and controlled torque are required. Its open-end design allows engagement with fasteners that cannot be accessed by a socket, making it practical for tight-clearance installations. Technicians working on equipment panels, gas valve fittings, and mechanical assemblies will find it useful where metric fasteners are standard.
