The WILLIAMS COMFORT PRODUCTS QYO18A is a 9/16 inch open-end torque wrench head designed for precision fastening applications where controlled torque is required. This SAE-specification head accepts a Y-type shank with a 0.560-inch shank size, allowing it to interface with compatible torque wrench handles. It delivers a maximum torque rating of 58 foot-pounds, making it suitable for medium-duty fastener work on equipment and assemblies where over-torquing must be avoided. The center-of-fastener to retaining pin measurement is 3 inches. Technicians across HVAC, plumbing, and general mechanical trades use this type of interchangeable torque head when working in tight or specific-access applications.
