Williams Comfort Products QYO44A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYO44A is an open-end torque wrench head sized at 1 3/8 inches, designed for use with compatible torque wrench handles in professional fastening applications. This head accepts a Y-type shank measuring 0.560 inches and delivers a maximum torque output of 160 foot-pounds. The open-end design allows access to fasteners in confined or obstructed spaces where a standard socket cannot seat. The center of fastener to retaining pin distance measures 3 inches. This tool is intended for use by mechanical tradespeople, HVAC technicians, plumbers, and other service professionals who require precise torque application on SAE-standard fasteners.

The QYO44A torque wrench head is suited for residential and light commercial service work where SAE fastener sizes are common. Its open-end configuration makes it practical for installations and service calls involving pipe fittings, equipment mounting hardware, and mechanical assemblies where access is limited. The Y-type shank interface ensures a secure connection to the drive handle during torque application, reducing the risk of slippage on critical fasteners.
