Cdi Torque TCQJO56ARTH Torque Wrench Head 1 3/4 in Sae

Product Description

The CDI TORQUE TCQJO56ARTH is an open-end thin torque wrench head designed for precision fastening applications in trade and mechanical service environments. Built to SAE measurement standards, this head fits a J-type shank with a 0.425-inch shank diameter and handles a maximum torque of 60 ft-lb. The 1 3/4-inch open-end thin profile allows access to fasteners in tight or recessed spaces where standard wrench heads cannot reach. It is suited for HVAC technicians, plumbers, pipefitters, and mechanical contractors who require accurate torque application on larger fasteners without sacrificing tool clearance.

This torque wrench head is intended for use in commercial and residential mechanical service work where fastener torque accuracy and limited access are both concerns. The open-end thin design is particularly useful when working around compressor fittings, flange bolts, and structural connection points that restrict full socket or box-end access. It pairs with compatible J-shank torque wrench handles to deliver repeatable torque values in the field or shop.

Key Features

• 1 3/4-inch open-end thin head for clearance-restricted fastener access
• Maximum torque rating of 60 ft-lb for controlled tightening on larger fasteners
• SAE measurement standard for compatibility with standard inch-based fastener systems
• J-type shank with 0.425-inch diameter for secure wrench handle connection
• Lightweight at 0.6 pounds for reduced hand fatigue during extended service work

Compatibility

Designed for use with J-shank torque wrench handles that accept a 0.425-inch shank diameter. Intended as an interchangeable torque head for mechanical, HVAC, plumbing, and pipefitting applications requiring SAE open-end fastener engagement.

Installation Notes

This torque wrench head is installed and used by licensed mechanical trades professionals including HVAC technicians, plumbers, and pipefitters. Ensure the torque wrench handle is set to the correct ft-lb value before applying load, and verify the shank is fully seated and secured before use. Always de-energize or depressurize the system being serviced before torquing fasteners on pressurized components. Follow applicable mechanical and HVAC codes for required torque specifications on the fasteners being serviced.
