The WILLIAMS COMFORT PRODUCTS QYO30A is a 15/16 inch open-end torque wrench head designed for precise fastener tightening in professional trade applications. It accepts a Y-type shank with a 0.560 inch shank size and delivers a maximum torque of 160 ft-lb, making it capable of handling demanding fastening tasks. The center-of-fastener to retaining pin measurement is 3 inches. This head is sold individually and is intended for use by mechanics, HVAC technicians, plumbers, and other trade professionals who require accurate torque application in tight or hard-to-reach spaces.
The QYO30A open-end torque wrench head is suited for residential and commercial trade work where a standard socket cannot be used due to fastener geometry or access constraints. It fits onto compatible torque wrench handles and is appropriate for SAE fastener applications. The open-end design allows engagement with hex fasteners from the side, which is useful in confined installation environments common in mechanical rooms, equipment closets, and rooftop units.
Designed as an OEM-style replacement torque wrench head for use with compatible Y-shank torque wrench handles requiring a 15/16 inch open-end SAE fitting.
Installation and use should be performed by a qualified trade professional familiar with torque specifications for the fasteners being serviced. Ensure the wrench handle and head shank connection are fully seated and the retaining pin is secured before applying torque. Do not exceed the 160 ft-lb maximum torque rating of this head. Consult applicable mechanical codes and equipment manufacturer torque specifications before use.
