Williams Comfort Products QJO48A Torque Wrench Head Open End

Product Description

The WILLIAMS COMFORT PRODUCTS QJO48A is a 1.5-inch open-end torque wrench head designed for precision fastening applications where controlled torque is critical. Built on a J-type shank measuring 0.425 inches, this wrench head accepts a mating torque wrench handle and delivers a maximum torque output of 60 foot-pounds. The center-of-fastener to retaining pin measurement is 2.5 inches, an important dimension when working in tight or offset clearances. This head follows SAE sizing standards and is suited for use by mechanics, HVAC technicians, plumbers, and other trade professionals who require repeatable torque values on threaded fasteners.

The QJO48A open-end torque wrench head is intended for use in applications where a standard closed socket cannot engage the fastener, such as inline fittings, hydraulic line connections, and other confined-access fastener points. Its J-type shank interfaces with compatible torque wrench handles, making it a practical addition to a field technician toolkit wherever SAE-sized open-end access is needed in place of a fixed combination wrench.

Compatibility

Designed for use with J-type torque wrench handles that accept a 0.425-inch J-shank drive head. Intended for SAE fastener applications requiring an open-end head profile.

Installation Notes

Install and remove this torque wrench head only when the torque wrench handle is not under load. Ensure the retaining pin is fully engaged before applying torque to prevent the head from disengaging during use. Always confirm the torque wrench handle is set to the correct foot-pound value before fastening. Use by qualified trade personnel in accordance with applicable service procedures and equipment manufacturer guidelines.
