Williams Comfort Products QZO38ADP Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO38ADP is an open-end torque wrench head designed for high-torque fastening applications in industrial and heavy-duty service environments. Built to SAE standards, this head accepts a Z dual-pin shank connection and delivers a maximum torque of 433 foot-pounds, making it suitable for large-diameter fasteners where controlled torque is critical. The 1 3/16-inch open-end head size accommodates specific fastener dimensions, and the dual-pin retention system keeps the head securely seated on the drive tool during use. Mechanics, millwrights, and industrial service technicians are the primary installers of this type of tooling.

This torque wrench head is intended for use with compatible CDI torque wrench drive handles that accept the Z dual-pin shank. It is suited for industrial maintenance, heavy equipment service, and structural bolting applications where precise torque output and a specific open-end head geometry are required. The center-of-fastener to retaining-pin measurement of 5 3/4 inches is a key dimensional reference for clearance planning in confined or close-tolerance work areas.

Key Features

• 1 3/16-inch open-end head for SAE fastener sizing
• Z dual-pin shank for positive retention on compatible drive handles
• Maximum torque capacity of 433 foot-pounds

Compatibility

Designed for use with CDI torque wrench handles that accept the Z dual-pin shank interface. Confirm shank compatibility with the drive handle before installation.

Installation Notes

Installation and use should be performed by qualified mechanics or industrial technicians familiar with torque wrench head systems. Ensure the dual-pin shank is fully seated and retained in the drive handle before applying load. Do not exceed the rated maximum torque of 433 foot-pounds. Inspect the head and retention pins for wear or damage before each use.
