Williams Comfort Products QYD12A-80 Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYD12A-80 is a square ratcheting torque wrench head designed for precise fastener torque application in trade and industrial settings. Built for a 3/8 inch drive, it accepts a Y-type shank measuring 0.560 inches and delivers up to 100 foot-pounds of maximum torque. The SAE configuration makes it a practical tool for HVAC, plumbing, and mechanical technicians who require consistent torque control during equipment installation and service work. Its compact profile allows use in tighter spaces where a full-handle torque wrench may not fit.

This torque wrench head is suited for residential and light commercial service work where fastener torque specifications must be met. It is typically used by HVAC technicians, plumbers, and mechanical contractors during equipment installation, component replacement, and preventive maintenance tasks. The ratcheting square head design allows the technician to drive fasteners without repositioning the tool on every stroke, improving efficiency in repetitive applications.

Installation Notes

Installation and use should be performed by a qualified trades technician familiar with torque fastening procedures. Ensure the drive coupling is fully seated before applying torque to prevent slippage or rounding of fasteners. Do not exceed the 100 foot-pound maximum torque rating of this head. Always power down or isolate the equipment being serviced before performing any fastener work on energized assemblies.
