Williams Comfort Products QJOM8A Torque Wrench Head 8MM

Product Description

The WILLIAMS COMFORT PRODUCTS QJOM8A is an 8 MM open-end torque wrench head designed for precision fastening in metric applications. The head accepts a J-type shank measuring 0.425 inches and is rated for a maximum torque of 10 ft-lb. This interchangeable torque head mounts to a compatible J-shank torque wrench handle, allowing technicians to switch drive sizes without replacing the entire tool. It is built for trade professionals who need accurate, repeatable torque application on metric fasteners in tight or specific-access locations.

This torque wrench head is suited for HVAC, plumbing, and mechanical service work where metric fasteners require controlled torque values. Its open-end design provides clearance for fasteners that cannot accept a socket-style drive. The compact head profile makes it practical in confined spaces, such as equipment panels, mounting brackets, and component housings. Technicians working on metric hardware in residential and light commercial service applications will find this head a standard addition to an interchangeable torque wrench set.
