Williams QYO22A Torque Wrench Head 11/16 Inch Open End

Product Description

The WILLIAMS QYO22A is an open-end torque wrench head designed for use with compatible torque wrench handles in precision fastening applications. Sized at 11/16 inch with a Y-type shank measuring 0.560 inches, this head transfers measured torque directly to fasteners where a standard socket cannot reach. Maximum torque capacity is 99 ft-lb, making it suitable for medium-duty fastening work in mechanical, HVAC, and plumbing service environments. The center of fastener to retaining pin dimension is 3 inches, which affects clearance planning in tight installations. Installed by mechanics and trade technicians who require controlled torque on open-fastener geometry.

This torque wrench head is suited for SAE fastening tasks in residential and commercial service work. It is commonly used in situations where a closed-end socket or box wrench cannot engage the fastener due to space or geometry constraints. The open-end design allows side-entry onto fastener flats, and the Y-type shank interfaces with the corresponding torque wrench handle. Typical applications include equipment assembly, piping connections, and mechanical component installation requiring repeatable torque values up to 99 ft-lb.

Compatibility

Designed for use with torque wrench handles that accept a Y-type shank measuring 0.560 inches. Confirm handle shank compatibility before installation.

Installation Notes

Installation is performed by qualified mechanics or trade technicians familiar with torque wrench systems. Ensure the torque wrench handle is set to the correct torque value before applying load, and verify the Y-type shank is fully seated and retained before use. Do not exceed the 99 ft-lb maximum torque rating. Follow applicable equipment manufacturer service procedures and relevant trade codes when torquing critical fasteners.
