Williams Comfort Products QJSD12A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QJSD12A is a fixed square drive torque wrench head designed for use with compatible torque wrench handles that accept a J-type shank. The head features a 3/8 inch drive and a 0.425 inch J-type shank, allowing it to deliver controlled torque output up to 60 foot-pounds. This type of interchangeable torque head is used by mechanics, HVAC technicians, plumbers, and other trade professionals who require precise fastener torque in confined or specialized applications where a standard fixed-handle wrench is impractical.

The QJSD12A is suited for light-to-medium duty fastening tasks across residential and commercial service work. Its compact fixed square drive profile makes it appropriate for use in tight service spaces where a full-length torque wrench cannot be positioned. It is sold as a single unit and is compatible with J-shank torque wrench handle systems that accept interchangeable heads.
