Cdi QJD16A 1/2 Inch Drive Torque Wrench Interchangeable Head

Product Description

The CDI QJD16A is a square ratcheting torque wrench interchangeable head designed for use with CDI modular torque wrench systems. Featuring a 1/2 inch square drive and a maximum torque capacity of 60 ft-lb, this head swaps into compatible CDI interchangeable-head wrenches to extend their range of application without requiring a separate full wrench assembly. The compact ratcheting head measures 3.54 inches in length, 1.57 inches in width, and 1.38 inches in height, and weighs under 1 pound. It is installed by licensed mechanics, HVAC technicians, plumbers, and other trade professionals who rely on CDI torque systems for calibrated fastening work.

This interchangeable head fits CDI modular torque wrench platforms used in both residential and commercial service environments. It is appropriate for applications requiring controlled torque in confined spaces where a full-length wrench is impractical. The square ratcheting design allows for incremental fastening without repositioning the wrench body, making it well suited for compressor bolting, flange work, and equipment panel fastening tasks where repeat engagement is needed.

Key Features

• 1/2 inch square drive for broad socket compatibility
• 60 ft-lb maximum torque rating for medium-duty fastening applications
• Square ratcheting head allows continuous fastening without repositioning
• Interchangeable design compatible with multiple CDI torque wrench handles
• Compact form factor at 3.54 inches long for use in tight spaces

Compatibility

Designed for use with the following CDI torque wrench handles: 50NMIMH, 100NIMIMH, 75MFIMHSS, 5T-I, 10T-I, 10ST-I, and 50T-I CDI Torque Wrenches.

Installation Notes

This head is installed and removed by hand using the CDI interchangeable-head attachment mechanism on a compatible wrench handle. Verify the head is fully seated and locked before applying torque. Technicians should follow applicable ASME B107 or equipment manufacturer torque specifications when using this head in calibrated torque applications. Do not exceed the 60 ft-lb rated maximum torque to avoid damage to the head or the wrench handle.
