Williams Comfort Products QZX34A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZX34A is a torque wrench head designed for high-load fastening applications where accurate torque delivery is critical. Built with a 15-degree offset box end and a 12-point configuration, it fits into tight or angled work areas that a straight head cannot reach. The shank measures 0.990 inches and uses a Z-type shank interface for secure engagement with compatible torque wrenches. Maximum rated torque is 480 foot-pounds, making it suitable for heavy-duty bolted connections in mechanical, industrial, and trade service environments. At 1.05 pounds, the head is solid without adding unnecessary bulk to the tool assembly.

This torque wrench head is used in applications requiring precise tightening of large fasteners, particularly where a standard inline head would not clear surrounding components. The 15-degree offset allows access to fasteners set at an angle or recessed in confined spaces. It is commonly used by mechanical contractors, millwrights, pipefitters, and industrial service technicians working on flanged connections, large HVAC equipment mounts, or structural mechanical assemblies. The 1-1/16 inch size is a common specification for heavy mechanical fasteners found in commercial and industrial settings.

Key Features

• Compact profile at 3.15 inches long and 0.43 inches tall for space-constrained access

Compatibility

Designed for use with torque wrenches that accept a Z-type shank interface with a 0.990-inch shank diameter. Confirm shank compatibility with your torque wrench before installation.

Installation Notes

This head is installed by mechanical trades including pipefitters, millwrights, and HVAC technicians working on heavy bolted assemblies. Ensure the fastener and wrench head are fully engaged before applying torque to prevent rounding or slippage. Always verify the torque wrench is calibrated and set to the job specification before use. Do not exceed the 480 foot-pound rated maximum torque for this head.
