Williams Comfort Products QZD24B Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZD24B is a square ratcheting torque wrench head designed for high-load fastening applications where precise torque application is critical. Built around a 3/4 inch drive, this head accepts standard 3/4 inch drive torque wrenches and delivers up to 480 ft-lb of maximum torque output. The Z-type shank measures 0.990 inches in diameter, providing a secure, low-slop interface with compatible drive tools. This type of interchangeable torque head is commonly used by industrial mechanics, heavy equipment technicians, and trade professionals working on structural, mechanical, or process piping assemblies where high-torque fastener work is required.

This torque wrench head is suited for SAE fastener applications in heavy-duty service environments. Its square ratcheting head design allows for use in confined or angled installation points where a standard fixed-head wrench cannot be positioned correctly. Typical applications include large-diameter flange bolting, structural steel assembly, and equipment installation requiring controlled, high-torque fastening within industrial or commercial settings.

Key Features

• 3/4 inch drive size for compatibility with standard 3/4 inch drive torque wrenches
• Square ratcheting head design for use in restricted-access fastening positions
• Maximum torque rating of 480 ft-lb for heavy-duty applications
