Williams Comfort Products QXOM20A Torque Wrench Head 20MM

Product Description

The WILLIAMS COMFORT PRODUCTS QXOM20A is a 20 MM open-end torque wrench head designed for precision torque application in professional trade and mechanical service work. Featuring an X-type shank measuring 0.735 inches, this head attaches to compatible torque wrench drive handles and delivers a maximum torque capacity of 160 ft-lb. At 0.48 pounds, it is a compact, purpose-built accessory suited for use in tight spaces where a standard closed-end head cannot seat properly. Licensed mechanics, HVAC technicians, and plumbers rely on open-end torque heads when fastener access is limited to a single side.

This torque wrench head is intended for metric fastener applications where controlled, measured torque is required. The 20 MM open-end jaw fits standard metric hex fasteners commonly found in HVAC equipment, plumbing assemblies, and mechanical systems. It is sold as a single unit and is appropriate for both shop and field service environments where repeatable torque accuracy is essential to proper installation and equipment longevity.

Compatibility

Installation Notes

Installation should be performed by a qualified mechanic or trade professional familiar with torque wrench equipment and proper fastener torque procedures. Confirm the shank is fully seated and locked into the drive handle before applying torque. Do not exceed the maximum rated torque of 160 ft-lb to avoid tool damage or fastener failure. Always consult the equipment manufacturer's torque specifications for the fasteners being serviced.
