The WILLIAMS COMFORT PRODUCTS QYXD30A is a 15/16-inch SAE torque wrench head designed for precision fastening in demanding trade applications. It features a 12-point contact design and accepts a 0.560-inch Y-shank drive. The head is rated to a maximum torque of 160 ft-lb, making it suitable for high-load fastening tasks found in HVAC equipment assembly, plumbing installations, and mechanical service work. Licensed technicians and professional tradespeople working with torque-critical fasteners rely on this style of interchangeable head for consistent, repeatable results when using compatible torque wrench handles.
This torque wrench head is suited for residential and commercial service environments where SAE fastener sizes are standard. The 15/16-inch opening targets common bolt and nut sizes found on equipment mounting hardware, flange fittings, and structural fasteners across HVAC, plumbing, and general mechanical trades. The interchangeable head design allows it to be swapped onto a compatible Y-shank torque wrench handle without requiring a separate full wrench assembly for each fastener size.
Designed for use with torque wrench handles that accept a 0.560-inch Y-shank drive. Specific handle compatibility should be confirmed against the handle manufacturer's interchangeable head specifications before installation.
This head is installed by qualified tradespeople familiar with torque wrench systems. Always verify that the shank is fully seated in the wrench handle before applying load. Do not exceed the rated maximum torque of 160 ft-lb. Inspect the head and shank for wear or damage before each use, and remove from service if any deformation is observed.
