Williams Comfort Products QZX48A Torque Wrench Head Sae

Product Description

The WILLIAMS COMFORT PRODUCTS QZX48A is a torque wrench head engineered for high-load fastening applications in mechanical, industrial, and trade settings. This head features a 15-degree offset box end with a 12-point configuration, allowing access to fasteners in tight or angled spaces. The 1.5-inch drive size and Z-type shank interface with compatible torque wrenches to deliver controlled torque output up to 480 ft-lb. At 1.35 pounds, the head is solid enough for heavy-duty work while remaining manageable during overhead or confined-space installations. Licensed technicians and journeymen mechanics working on large-diameter fasteners will find this head suited to demanding service environments.

This torque wrench head is intended for use in commercial and industrial mechanical applications where precise torque is required on large fasteners. Typical use cases include equipment assembly, pipe flange bolting, and structural fastener work. The offset box end geometry helps clear obstructions around bolt heads, making it practical for installations where a standard straight head cannot seat properly. The 0.990-inch shank diameter is sized for compatibility with Z-shank torque wrench handles commonly used in professional trade settings.
