The CDI TORQUE TCQJO34ARTH is a 1-1/16 inch open end thin torque wrench head designed for precision fastening applications where accurate torque delivery is required. Built with a J-type shank measuring 0.425 inches, this head attaches to compatible CDI torque wrench handles and transmits torque to fasteners in tight or restricted access areas where standard sockets cannot reach. With a maximum torque rating of 60 ft-lb, it covers a broad range of mechanical fastening tasks encountered by HVAC technicians, plumbers, and general mechanical trades in daily service work.
This torque wrench head is suited for residential and light commercial service applications where SAE fastener sizes are standard. The open end thin profile allows access to fasteners in confined spaces such as equipment panels, manifold assemblies, and bracket hardware. It is typically used by service technicians who require controlled torque on hex fasteners without the clearance needed for a standard box or socket tool. The J-type shank design ensures a secure, repeatable connection to the drive handle.
Designed for use with CDI torque wrench handles that accept a J-type shank. Verify shank size and type compatibility with your existing handle before installation.
Installation should be performed by a qualified technician familiar with torque wrench tooling. Confirm the shank is fully seated and secured in the torque wrench handle before applying load. Do not exceed the 60 ft-lb maximum torque rating of this head. Store the wrench handle at its lowest torque setting when not in use to preserve internal spring calibration.
