Product Description

The WILLIAMS COMFORT PRODUCTS QJOM12A is a 12 MM open-end torque wrench head designed for precision fastening in metric applications. The head accepts a J-type shank with a 0.425-inch shank size and is rated for a maximum torque of 36 ft-lb. Built for trade use, this interchangeable torque head connects to compatible torque wrench handles, allowing technicians to swap head sizes without changing the entire tool. It is sold individually and is well suited for HVAC, plumbing, and mechanical service work where metric fasteners are encountered.
